It is narrated from Sayyiduna ‘Ubada (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) was going to attack enemy territory, he would give an extra fourth share, and when returning and the people were tired, he would give an extra third share. In fact, the Prophet (peace and blessings be upon him) disliked extra shares and said: The strong believer should return (his share) to the weak ones.
