Abu Hafs Amr bin Ibrahim bin Ahmad bin Katheer Al-Maqarri narrated from Abdullah bin Mohammad bin Abdil Aziz AloBaghawi, from Abdullah bin Omar, from Abdul MALIk bin Umair, from Salem Al-Bazzaz, from Abu Huraira, who said:
The MESSENGER OF ALLAH (SWT) said, “ALI BIN ABI TALEB (ASWS), FATEMA (SAWS) , HASAN (ASWS), and HUSAIN (ASWS) are the best of this nation after me. ALLAH (SWT)’s curse is on whoever says anything against this.”
