The Optional Salah (prayer)

2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ibn ’Udhaynah from ibn Faddal ibn Yasar who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘Obligatory and optional Salah (prayer) are fifty-one Rak‘at, of which there are two Rak‘at after al-‘Atmah in a sitting position which are counted as one Rak‘at in a standing position. Obligatory Salah (prayer) are seventeen Rak‘at and optional Salah (prayer) are thirty-four Rak‘at.’”
