Then the Prophet (peace and blessings be upon him) took a knife and began to cut pieces of that meat for me. Meanwhile, Sayyiduna Bilal (may Allah be pleased with him) came and informed the Prophet (peace and blessings be upon him) about the prayer. The Prophet (peace and blessings be upon him) put the knife down right there and said:“May Bilal’s hands be dusted (what would have happened if he had waited a little longer).”Sayyiduna Mughirah (may Allah be pleased with him) says: My moustache had grown long, so the Prophet (peace and blessings be upon him) placed a miswak underneath and trimmed it.
