Sayyiduna Abu Tha'labah al-Ashja'i (may Allah be pleased with him) said: I said: O Messenger of Allah! Two of my children have died while I was in Islam. The Messenger of Allah (peace and blessings be upon him) said: "Whoever has two children die while he is in Islam, Allah will admit him into Paradise by the bounty of His mercy towards those two."
