عن الحسن البصري قال من أراد أن يشرب بالكأس الأوفى من حوض المصطفى فليقل اللهم صل على محمد وعلى آله وأصحابه وأولاده وأزواجه وذريته وأهل بيته وأصهاره وأنصاره وأشياعه ومحبيه وأمته وعلينا معهم أجمعين يا أرحم الراحمين ذكره القاضي عياض في الشفاء (القول البديع ص123)

Hazrat Hasan Basri (rahimahullah) mentioned, “Whoever wishes to drink from the Howdh-e-Kawthar of Mustafa (sallallahu ‘alaihi wasallam) with the cup of full measure, then he should recite the following durood:

اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِهِ وَأَصْحَابِهِ وَأَوْلَادِهِ وَأَزْوَاجِهِ وَذُرِّيَّتِهِ وَأَهْلِ بَيْتِهِ وَأَصْهَارِهِ وَأَنْصَارِهِ وَأَشْيَاعِهِ وَمُحِبِّيْهِ وَأُمَّتِهِ وَعَلَينَا مَعَهُمْ أَجْمَعِيْنَ يَا أَرْحَمَ الرَّاحِمِيْنَ

O Allah! Send salutations upon Muhammed (sallallahu ‘alaihi wasallam), his family, his Sahaabah (radhiyallahu ‘anhum), his children, his wives, his progeny, his household, his relatives through marriage, his helpers (the Ansaar (radhiyallahu ‘anhum)), his followers, those who love him, his ummah, and upon us all with them, O Most Merciful of those who show mercy.
