Hadith 2213
Hazrat Abu Salamah (may Allah have mercy on him) says that I asked Sayyidah Aisha (may Allah be pleased with her), so I said, "Mother, tell me about the night prayer of the Messenger of Allah (peace and blessings of Allah be upon him)." She replied, "His night prayer during Ramadan and in other months was thirteen rak'ahs." This is the narration of Abdul Jabbar. And in the narration of Abu Hashim, it is stated: "I came to Sayyidah Aisha (may Allah be pleased with her) and I asked her about the prayer of the Messenger of Allah (peace and blessings of Allah be upon him) in Ramadan, so she replied, 'His prayer was thirteen rak'ahs. Among them were two rak'ahs of the Sunnah of Fajr.'"
