Surah Al-Hashr (59:9) Para 28
وَٱلَّذِينَ تَبَوَّءُو ٱلدَّارَ وَٱلْإِيمَـٰنَ مِن قَبْلِهِمْ يُحِبُّونَ مَنْ هَاجَرَ إِلَيْهِمْ وَلَا يَجِدُونَ فِى صُدُورِهِمْ حَاجَةً مِّمَّآ أُوتُوا۟ وَيُؤْثِرُونَ عَلَىٰٓ أَنفُسِهِمْ وَلَوْ كَانَ بِهِمْ خَصَاصَةٌ ۚ وَمَن يُوقَ شُحَّ نَفْسِهِۦ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ
"And [also for] those who were settled in the Home [i.e.,al-Madīnah] and [adopted] the faith before them.1 They love those who emigrated to them and find not any want in their breasts of what they [i.e., the emigrants] were given but give [them] preference over themselves, even though they are in privation. And whoever is protected from the stinginess of his soul - it is those who will be the successful."

Brotherhood (Mu'akhat) — Muhajirun Paired with Ansar

🔬 social

The Prophet (ﷺ) established a formal brotherhood (mu'akhat) between the Muhajirun (emigrants from Makkah) and the Ansar (helpers of Madinah). Each Makkan was paired with a Madinan counterpart who shared his property and home as if they were brothers. Sa'd ibn al-Rabi offered to give half his property and even offered his wife in divorce for his Makkan brother Abdur Rahman ibn Awf, who declined but was deeply moved.

Surah Al-Anfal (8:72) Para 10
إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَهَاجَرُوا۟ وَجَـٰهَدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّهِ وَٱلَّذِينَ ءَاوَوا۟ وَّنَصَرُوٓا۟ أُو۟لَـٰٓئِكَ بَعْضُهُمْ أَوْلِيَآءُ بَعْضٍ ۚ وَٱلَّذِينَ ءَامَنُوا۟ وَلَمْ يُهَاجِرُوا۟ مَا لَكُم مِّن وَلَـٰيَتِهِم مِّن شَىْءٍ حَتَّىٰ يُهَاجِرُوا۟ ۚ وَإِنِ ٱسْتَنصَرُوكُمْ فِى ٱلدِّينِ فَعَلَيْكُمُ ٱلنَّصْرُ إِلَّا عَلَىٰ قَوْمٍۭ بَيْنَكُمْ وَبَيْنَهُم مِّيثَـٰقٌ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ
"Indeed, those who have believed and emigrated and fought with their wealth and lives in the cause of Allāh and those who gave shelter and aided - they are allies of one another. But those who believed and did not emigrate - for you there is no support of them until they emigrate. And if they seek help of you for the religion, then you must help, except against a people between yourselves and whom is a treaty. And Allāh is Seeing of what you do."

Surah Al-Jumu'ah (62:9) Para 28
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نُودِىَ لِلصَّلَوٰةِ مِن يَوْمِ ٱلْجُمُعَةِ فَٱسْعَوْا۟ إِلَىٰ ذِكْرِ ٱللَّهِ وَذَرُوا۟ ٱلْبَيْعَ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ
"O you who have believed, when [the adhān] is called for the prayer on the day of Jumuʿah [Friday], then proceed to the remembrance of Allāh and leave trade. That is better for you, if you only knew."

First Adhan — Bilal ibn Rabah Calls to Prayer

🔬 worship

In the first year after Hijra, the Prophet consulted the Companions about how to call people to prayer. After Abdullah ibn Zayd (RA) saw the adhan in a dream and reported it to the Prophet, who confirmed it by revelation, Bilal ibn Rabah (RA) was chosen to make the first call to prayer. His powerful voice echoed over Madinah. Umar ibn al-Khattab also reported receiving the same words in a dream.

Surah Al-Ma'idah (5:58) Para 6
وَإِذَا نَادَيْتُمْ إِلَى ٱلصَّلَوٰةِ ٱتَّخَذُوهَا هُزُوًا وَلَعِبًا ۚ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْقِلُونَ
"And when you call to prayer, they take it in ridicule and amusement. That is because they are a people who do not use reason."

"The foolish among the people will say, "What has turned them away from their qiblah,1 which they used to face?"2 Say, "To Allāh belongs the east and the west. He guides whom He wills to a straight path.""

Change of Qibla — From Jerusalem to Makkah

🔬 worship

For 16–17 months after the Hijra, Muslims prayed facing Bayt al-Maqdis (Jerusalem). Then the verse was revealed: "Turn your face toward al-Masjid al-Haram" (2:144). The change occurred during a prayer at Masjid al-Qiblatain (Mosque of the Two Qiblas), when the verse was revealed mid-prayer and the congregation turned 180° to face Makkah. This change was a trial that distinguished true believers from hypocrites.

Surah Al-Baqarah (2:143) Para 2
وَكَذَٰلِكَ جَعَلْنَـٰكُمْ أُمَّةً وَسَطًا لِّتَكُونُوا۟ شُهَدَآءَ عَلَى ٱلنَّاسِ وَيَكُونَ ٱلرَّسُولُ عَلَيْكُمْ شَهِيدًا ۗ وَمَا جَعَلْنَا ٱلْقِبْلَةَ ٱلَّتِى كُنتَ عَلَيْهَآ إِلَّا لِنَعْلَمَ مَن يَتَّبِعُ ٱلرَّسُولَ مِمَّن يَنقَلِبُ عَلَىٰ عَقِبَيْهِ ۚ وَإِن كَانَتْ لَكَبِيرَةً إِلَّا عَلَى ٱلَّذِينَ هَدَى ٱللَّهُ ۗ وَمَا كَانَ ٱللَّهُ لِيُضِيعَ إِيمَـٰنَكُمْ ۚ إِنَّ ٱللَّهَ بِٱلنَّاسِ لَرَءُوفٌ رَّحِيمٌ
"And thus We have made you a median [i.e., just] community that you will be witnesses over the people and the Messenger will be a witness over you. And We did not make the qiblah which you used to face except that We might make evident who would follow the Messenger from who would turn back on his heels.1 And indeed, it is difficult except for those whom Allāh has guided. And never would Allāh have caused you to lose your faith [i.e., your previous prayers]. Indeed Allāh is, to the people, Kind and Merciful."

"We have certainly seen the turning of your face, [O Muḥammad], toward the heaven, and We will surely turn you to a qiblah with which you will be pleased. So turn your face [i.e., yourself] toward al-Masjid al-Ḥarām.1 And wherever you [believers] are, turn your faces [i.e., yourselves] toward it [in prayer]. Indeed, those who have been given the Scripture [i.e., the Jews and the Christians] well know that it is the truth from their Lord. And Allāh is not unaware of what they do."

And wherever you [believers] may be, turn your faces toward it in order that the people will not have any argument against you, except for those of them who commit wrong; so fear them not but fear Me. And [it is] so I may complete My favor upon you and that you may be guided,"

In the second year after Hijra, the obligation of Ramadan fasting was revealed: "O you who have believed, decreed upon you is fasting as it was decreed upon those before you, that you may become righteous" (2:183). The previous optional fast of Ashura (10th Muharram, Mosaic fast) was superseded. Ramadan fasting became one of the Five Pillars of Islam. Zakat al-Fitr was also prescribed at the end of Ramadan.

"[Fasting for] a limited number of days. So whoever among you is ill or on a journey [during them] - then an equal number of other days [are to be made up]. And upon those who are able [to fast, but with hardship] - a ransom [as substitute] of feeding a poor person [each day]. And whoever volunteers good [i.e., excess] - it is better for him. But to fast is best for you, if you only knew."

Allāh intends for you ease and does not intend for you hardship and [wants] for you to complete the period and to glorify Allāh for that [to] which He has guided you; and perhaps you will be grateful."

"It has been made permissible for you the night preceding fasting to go to your wives [for sexual relations]. They are a clothing for you and you are a clothing1 for them. Allāh knows that you used to deceive yourselves,2 so He accepted your repentance and forgave you. So now, have relations with them and seek that which Allāh has decreed for you [i.e., offspring]. And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]. Then complete the fast until the night [i.e., sunset]. And do not have relations with them as long as you are staying for worship in the mosques. These are the limits [set by] Allāh, so do not approach them. Thus does Allāh make clear His verses [i.e., ordinances] to the people that they may become righteous."

Expulsion of Banu Qaynuqa — First Jewish Tribe Exiled

🔬 battle

Shortly after Badr, the Banu Qaynuqa tribe violated the Constitution of Madinah by publicly insulting a Muslim woman and killing the Muslim who came to her aid. The Prophet (ﷺ) besieged their fortress for 15 days until they surrendered. Abdullah ibn Ubayy (the hypocrite leader) interceded for them. The Prophet exiled them north to Adhraat in Syria. This was the first expulsion of a Jewish tribe from Madinah.
