Qays bin Abi Hazim (may Allah have mercy on him) narrates that one day Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) addressed the people from the pulpit of Madinah, and said in his sermon: "In the Gardens of Eden there is a palace with five hundred doors; at every door there are five thousand of the wide-eyed maidens (hur al-'in); no one will enter it except a prophet." Then he (may Allah be pleased with him) looked towards the blessed grave of the Messenger of Allah (peace and blessings be upon him) and said: "Congratulations to you, O occupant of the grave!" Then he said: "Or a siddiq (will enter it)." Then he turned towards the grave of Sayyiduna Abu Bakr (may Allah be pleased with him) and said: "Congratulations to you, O Abu Bakr!" Then he said: "Or a martyr (will enter it)." Then he addressed himself and said: "O Umar! Where will martyrdom come to you from?" Then he said: "The One who brought me out of Makkah to the emigration to Madinah is able to drive martyrdom towards me." Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: "So Allah Almighty brought that martyrdom to him at the hands of the worst of creatures, a Magian slave belonging to al-Mughirah (may Allah be pleased with him)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Isma'il except Sharik; Muhammad bin al-Hasan is alone in it."
It is like this ('Hushaym') in the printed edition of Dar al-Haramayn, and perhaps the correct form is 'Haytham'.
