What did the hypocrites do during the lifetime of Prophet Muhammad (saw) that Allah (SWT) revealed in Qur'anic verse 3.188?
 Narrated Abu Sa`id Al-Khudri:                     During the lifetime of Allah's Apostle, some men among the hypocrites used to remain behind him (i.e. did not accompany him) when he went out for a Ghazwa and they would be pleased to stay at home behind Allah's Apostle When Allah's Apostle returned (from the battle) they would put forward (false) excuses and take oaths, wishing to be praised for what they had not done. So there was revealed:-- "Think not that those who rejoice in what they have done, and love to be praised for what they have not done.." (3.188)
