It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Those performing Hajj and Umrah are the guests of Allah; if they call upon Him, He answers them, and if they seek His forgiveness, He forgives them."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ya'qub bin Abbad (may Allah have mercy on him) except Salih bin Abdullah (may Allah have mercy on him), and Ibrahim bin al-Mundhir (may Allah have mercy on him) is alone in narrating it."
