Battle of Badr, Friday morning the 17th of Ramadan
Habban ibn Wasi ibn Habban (raa) told me on the Authority of some elders of his tribe that on the day of Badr the apostle dressed the ranks of his companion wth an arrow which he held in his hand.
As he passed by Sawad ibn Ghaziya (raa), an ally of Ibn’Adiy ibn al-Najjar (raa), who was mustansil (standing out of line) he pricked him in his belly with the arrow, saying, “Stand in line, O Sawad!” 
“You have hurt me, O apostle of Allah,” he cried, “and Allah has sent you with right and justice so let me retaliate.”
The apostle uncovered his belly and said “Take your retaliation.”
Sawad (raa) embraced him and kissed his belly. He asked what had made him do this and he replied, “O apostle of Allah, you see what is before us and I may not survive the battle and as this is my last time with you I want my skin to touch yours”.
The apostle blessed him.
Lessons to be learnt:
- Humility of Prophet (saws): He did not tell other soldiers to take him away and got tortured for what he said like leaders of our times would
- Justice of Prophet (saws) when he allowed the companion to retaliate
- The love the Sahaba (Companions) (raa) for Prophet (saws)
