It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever performs Hajj on behalf of a deceased person, the one on whose behalf the Hajj was performed will receive a reward equal to the reward of the one who performed it. Whoever gives a fasting person something to break his fast with will receive a reward equal to the reward of that fasting person. And whoever guides to something good will receive a reward equal to the reward of the one who does it."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ibn Jurayj (may Allah have mercy on him) except Abd al-Malik bin Abi Karimah; Ali bin Bahram is alone in narrating it."
