{ Spend for the sake of Allah, and do not be thrown into ruin by your own hands; and do good, indeed Allah loves those who do good } Al-baqara 195

{ Spend for the sake of Allah } : in obedience to Him by jihad and otherwise; { and do not be thrown … by your own hands } : that is, do not throw yourselves (the “by” is additional); { into ruin } : destruction, by holding back from spending for jihad, or abandoning it, since this would strengthen the enemy against you.
