It is narrated from Musa رحمه الله, he says: I asked Sayyiduna Ibn Abbas رضي الله عنهما, "How should I perform prayer in Makkah Mukarramah if I have not prayed with the congregation?" He replied, "Pray two rak‘ahs according to the Sunnah of Abu al-Qasim صلى الله عليه وسلم." Bundar says: I heard Qatadah, he narrates from Musa bin Salamah that I asked Sayyiduna Ibn Abbas رضي الله عنهما.
