Lady Aisha Siddiqa (may Allah be pleased with her) narrates: The Prophet Muhammad (peace and blessings be upon him) gathered his family and said: When any of you is afflicted with grief or calamity, let him recite these words: "Allah is my Lord, I do not associate anyone with Him." The narrator named Abu Amir Khazzaz is Salih bin Rustam. Forty narrations have been transmitted from him, and he is among the trustworthy narrators from Basra.
