Sayyiduna Muhammad bin Ammar bin Yasir (may Allah be pleased with him) says: I saw Ammar bin Yasir (may Allah be pleased with him) perform six rak‘ahs after Maghrib, so I said: Father! What prayer is this? He said: I saw my beloved, the Messenger of Allah (peace and blessings be upon him), perform six rak‘ahs after Maghrib and he said:“Whoever prays six rak‘ahs after Maghrib, his sins are forgiven even if they are like the foam of the sea.”
