باب الْجَعَائِلِ وَالْحُمْلاَنِ فِي السَّبِيلِ
Mujahid said, "Once I said to Ibn 'Umar, 'Let us proceed for Jihad.' Ibn 'Umar replied, 'I would like to support you with some of my money.' I replied, 'Allah has given me enough.' He said, 'Your wealth is for you, but I like that some of my money be spent in this cause.'"
'Umar said, "Some people take money (from the Muslim’s Treasury) to strive in Allah’s Cause, but they don’t strive. So, if someone does so, we have the right to take back whatever he has taken."
Tawus and Mujahid said, "If something is given to you, so that you may strive in Allah’s Cause, then do whatever you like with it and keep it with your family."
