"The Prophet sent Abdullah bin Rawahah to lead a military detachment, and that corresponded to a Friday. So his companions left early in the day, and he said: 'I will remain behind to pray with Allah's Messenger then meet up with them.' When he prayed with the Prophet, he saw him and said: 'What prevented you from leaving earlier with your companions?' He said: 'I wanted to pray with you then meet up with them.' He said: 'If you have spent [all of] what is in the earth, you would not have achieved the virtue you have had you left early in the day with them.'"
