It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that he said: "I gave a she-camel in the path of Allah, then I intended to buy an animal from its offspring, or (the narrator) said: from its own stock. So I asked the Prophet (peace and blessings be upon him) about this, and he (peace and blessings be upon him) said: 'Leave it, so that on the Day of Resurrection it and all its young come together in your scale (of deeds).'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Shu'bah (may Allah have mercy on him) except Mu'ammal (may Allah have mercy on him)."
