فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌۭ وَرِثُوا۟ ٱلْكِتَٰبَ يَأْخُذُونَ عَرَضَ هَٰذَا ٱلْأَدْنَىٰ وَيَقُولُونَ سَيُغْفَرُ لَنَا وَإِن يَأْتِهِمْ عَرَضٌۭ مِّثْلُهُۥ يَأْخُذُوهُ ۚ أَلَمْ يُؤْخَذْ عَلَيْهِم مِّيثَٰقُ ٱلْكِتَٰبِ أَن لَّا يَقُولُوا۟ عَلَى ٱللَّهِ إِلَّا ٱلْحَقَّ وَدَرَسُوا۟ مَا فِيهِ ۗ وَٱلدَّارُ ٱلْءَاخِرَةُ خَيْرٌۭ لِّلَّذِينَ يَتَّقُونَ ۗ أَفَلَا تَعْقِلُونَ

Sahih al-Bukhari
Merits of the Helpers in Madinah (Ansaar)
Chapter: “O Allah! Improve and make right the state of the Ansar and the Muhajirun
Narrated Anas bin Malik:
On the day of the battle of the Trench (i.e. Ghazwat-ul-Khandaq) the Ansar used to say, "We are those who have given the pledge of allegiance to Muhammad for Jihad (i.e. holy fighting) as long as we live." The Prophet (ﷺ) , replied to them, "O Allah! There is no life except the life of the Hereafter; so please honor the Ansar and the Emigrants."
