Mistake in the Morning, al-Maghrib and Friday Salah (Prayer)

2. Ali ibn Ibrahim has narrated from his father from Hammad, from Hariz from Muhammad ibn Muslim who has said the following: “I once asked abu ‘Abd Allah عليه السلام, about a man who performs Salah (prayer) but does not know if he has performed one or two (Rak‘at). He (the Imam) said, ‘He performs it again to ascertain that he has completed it and so also is the case with Friday, al-Maghrib and Salah (prayer) on a journey.’”
