It is narrated from Abdullah bin Sa’ib (may Allah be pleased with him), he states: The Messenger of Allah (ﷺ) led us in the morning prayer in Makkah. He began reciting Surah Al-Mu’minun, and when he reached the mention of Musa and Harun (peace be upon them), or the mention of Isa (peace be upon him), the Prophet (ﷺ) started coughing, so he left the recitation and went into bowing (ruku’). The narrator says that Abdullah bin Sa’ib (may Allah be pleased with him) was present in that prayer.
