Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "Whoever builds a mosque for Allah Almighty, Allah Almighty builds for him a house in Paradise, and if he dies that same day, Allah Almighty forgives him. And whoever digs a grave for the pleasure of Allah Almighty, Allah Almighty builds for him a house in Paradise, and if he dies that same day, Allah Almighty forgives him."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Imran bin Abdullah, who is in fact Ibn Ubaydullah. Imam al-Bukhari (may Allah have mercy on him) mentioned him in his Tarikh and said: There is room for reservation about him (fihi nazar). Yahya bin Ma'in also declared him da'if (weak). Ibn Hibban mentioned him in the book "al-Thiqat" and gave his father's name as Abdullah, in the non-diminutive form (mukabbar).
