Musannaf Ibn Abi Shaybah

Hazrat Abu Musa (may Allah be pleased with him) narrates that after the conquest of Khaybar, we joined the army of the Prophet (peace and blessings be upon him), so the Prophet (peace and blessings be upon him) granted us a share from the spoils of war, and did not grant a share to anyone else who had not participated in the battle.

It is narrated from Hazrat Aamir (may Allah be pleased with him) that Hazrat Umair (may Allah be pleased with him) wrote to Hazrat Saad bin Abi Waqqas (may Allah be pleased with him) on the day of Qadisiyyah: I am sending to you the people of Hijaz and Shaam; whoever among them joins the battle before the corpses become spoiled, give him a share in the spoils.

It is narrated from Hazrat Ibn Abi Habib (may Allah be pleased with him) that Hazrat Abu Bakr Siddiq (may Allah be pleased with him) sent Hazrat Ikrimah bin Abi Jahl to assist Muhajir bin Abi Umayyah and Ziyad bin Labid. When he reached them, they had already achieved victory, and their bodies, covered in blood, were present. He included them as well in the spoils of war.

It is narrated from Hazrat Hakam (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) gave a share from the spoils of war on the day of Khaybar to Ja'far and his companions, even though they had not participated in the Battle of Khaybar.
