Documentation of the land grants
وَقَالَ اللَّيْثُ عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ أَنَسٍ ـ رضى الله عنه ـ دَعَا النَّبِيُّ صلى الله عليه وسلم الأَنْصَارَ لِيُقْطِعَ لَهُمْ بِالْبَحْرَيْنِ، فَقَالُوا يَا رَسُولَ اللَّهِ إِنْ فَعَلْتَ فَاكْتُبْ لإِخْوَانِنَا مِنْ قُرَيْشٍ بِمِثْلِهَا، فَلَمْ يَكُنْ ذَلِكَ عِنْدَ النَّبِيِّ صلى الله عليه وسلم فَقَالَ " إِنَّكُمْ سَتَرَوْنَ بَعْدِي أَثَرَةً فَاصْبِرُوا حَتَّى تَلْقَوْنِي ".
Narrated Anas (ra): The Prophet (ﷺ) called the Ansar so as to grant them a portion of (the land of) Bahrain. They said, "O Allah's Messenger (ﷺ) ! If you grant this to is, write a similar document on our Quraish (emigrant) brothers." But the Prophet (ﷺ) did not have enough grants and he said: "After me you will see the people giving preference (to others), so be patient till you meet me."
