It is narrated from the Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her), that the Prophet (peace and blessings be upon him) recited (Surah al-Kawthar in this way): 'Inna antaynaka al-Kawthar' (Indeed, We have given you al-Kawthar).
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) only with this chain; Amr bin Mukharram is alone in narrating it."
