Surah Al Ahzab Calligraphy - 33

إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنْكُمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًا

 Translation: 

Allah only wishes to remove uncleanliness from you, O members of the (Prophet’s) household, and to purify you completely. 

This is part of a verse 33 in surat al-ahzab(33), Allah addressing  specifically the prophet and his wives, also applies to  Ali, Fatima , Alhassan and Alhussein. Majority of scholars say also applies to Al-abbas and Aqeel which were the prophet uncles, and some say anyone wasn't entitled for sadaqah money from his family, bani hashim and bani almuttalib.
