´It was narrated from Umm Salamah, the wife of the Prophet (ﷺ), that the Messenger of Allah (ﷺ) said:` “Whoever begins the Talbiyah for ‘Umrah from Baitul-Maqdis, that will be an expiation for all his previous sins.” She said: “So I went out.” Meaning, from Baitul-Maqdis for ‘Umrah.

Narrated Umm Salamah, Ummul Muminin: She heard the Messenger of Allah ﷺ say: If anyone puts on ihram for hajj or Umrah from the Aqsa mosque to the sacred mosque, his former and latter sins will be forgiven, or he will be guaranteed Paradise. The narrator Abdullah doubted which of these words he said. Abu Dawud said: May Allah have mercy on Waki. He put on ihram from Jerusalem (Aqsa mosque), that is, to Makkah.

1741. Commentary: The narration of Umm Salamah (radi Allahu anha) has much difference in its chain of transmission and text. (Munziri and others) Although it is established from several Companions and Followers (Tabi'in) that they assumed ihram before reaching the miqat, yet from the explicit statement of the Messenger of Allah (sallallahu alayhi wa sallam) that "He designated these specific stations (manazil)," it is established that assuming ihram from these locations is the Sunnah of the Prophet and the most virtuous act. (For details, see: Mir'at al-Mafatih, Hadith no: 2540)
