Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) was travelling on a journey when suddenly a woman came with her son and said: "O Messenger of Allah, does this child also have a Hajj?" He (peace and blessings be upon him) said: "Yes, and you will also have a reward." She asked: "When he stands at Arafah, what is his reward?" He (peace and blessings be upon him) said: "Good deeds are recorded for his parents equal to the number of the hairs on the heads of every person who stands on the plain of Arafat."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith has not been narrated from Imam al-Zuhri (may Allah have mercy on him) by any chain other than this one, and al-Tarjumani is alone in narrating it."
