[Machine] "Come with us to the Messenger of Allah ﷺ so that we may ask him to make our water flow abundantly, as we are facing a severe drought. We have never asked him for anything except that he has given it to us, and he never asks anything of his Lord except that it is granted to him. So they went to the Messenger of Allah ﷺ and he came out to meet them, saying, 'Welcome to the Ansar (the helpers).' He repeated this three times and said, 'Do not ask me for anything today except that I will give it to you, and I do not ask my Lord for anything except that He grants it to me.' They abandoned their request and said, 'O Messenger of Allah, pray to Allah for our forgiveness.' The Messenger of Allah ﷺ said, 'O Allah, forgive the Ansar, their children, and the children of their children.'"  

الكبرى للنسائي:١٠٠٧٣أَخْبَرَنَا عَبْدَةُ بْنُ عَبْدِ اللهِ قَالَ حَدَّثَنَا حَرَمِيُّ بْنُ حَفْصٍ قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنِ مُسْلِمٍ قَالَ حَدَّثَنَا يَزِيدُ بْنُ أَبِي زِيَادٍ عَنْ ثَابِتٍ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ اجْتَمَعَتِ الْأَنْصَارُ فَقَالَ

انْطَلِقُوا بِنَا إِلَى رَسُولِ اللهِ ﷺ فَنَسْأَلُهُ أَنْ يَجْعَلَ مَاءَنَا سَيْحًا فَقَدِ اشْتَدَّ عَلَيْنَا النَّوَاضِحُ وَإِنَّا لَمْ نَسْأَلْهُ شَيْئًا إِلَّا أَعْطَانَا وَلَنْ يَسْأَلَ رَبَّهُ شَيْئًا إِلَّا أَعْطَاهُ فَأَتَوْا رَسُولَ اللهِ ﷺ فَخَرَجَ عَلَيْهِمْ فَقَالَ «مَرْحَبًا بِالْأَنْصَارِ يَقُولُهَا ثَلَاثًا لَا تَسْأَلُونِي الْيَوْمَ شَيْئًا إِلَّا أَعْطَيْتُكُمْ وَلَا أَسْأَلُ رَبِّي إِلَّا أَعْطَانِيهِ» فَتَرَكُوا مَسْأَلَتَهُمُ الَّتِي جَاؤوا فِيهَا فَقَالُوا يَا رَسُولَ اللهِ ادْعُ اللهَ لَنَا بِالْمَغْفِرَةِ فَقَالَ رَسُولُ اللهِ ﷺ «اللهُمَّ اغْفِرْ لِلْأَنْصَارِ وَلِأَبْنَاءِ الْأَنْصَارِ وَلِأَبْنَاءِ أَبْنَاءِ الْأَنْصَارِ»
