It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever enters ihram from Bayt al-Maqdis (Jerusalem) will enter (Makkah) forgiven (in a state in which he has already been forgiven)."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Ghalib bin Ubaydullah narrated this hadith from Nafi', and Musa bin Ayyub is alone in it."
