التواب
التوبةُ هي الرجوع عن الذَّنب، و(التَّوَّاب) اسمٌ من أسماء الله...
Wā’il ibn Hujr (may Allah be pleased with him) reported: I prayed with the Prophet (may Allah's peace and blessings be upon him) and he used to make Taslīm to his right, saying: "Peace be upon you, and the mercy of Allah and His blessings" and to his left, saying: "Peace be upon you, and the mercy of Allah."
شرح الحديث :
The Hadīth indicates that the person who is offering the prayer does not exit his prayer except by offering two Taslīms, one to the right and one to the left. He says in the first: "Peace be upon you, and the mercy of Allah and His blessings", and in the second: "Peace by upon you, and the mercy of Allah."
