"I heard Muas- bin Salamah-say: 'I said to Ibn 'Abbas: How should I pray in Makkah if I do not pray in congregation? He said: Two rak'ahs, the sunnah of Abu Al-Qasim.'" (Using translation from Nasāʾī 1443)
قُلْتُ لِابْنِ عَبَّاسٍ كَيْفَ أُصَلِّي بِمَكَّةَ إِذَا لَمْ أُصَلِّ فِي جَمَاعَةٍ؟ قَالَ «رَكْعَتَيْنِ سُنَّةَ أَبِي الْقَاسِمِ ﷺ»
