It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that he said: Jihad is of two types. One is the jihad in which the best of wealth is spent, love is shown to companions, obedience is given to the leader, and mischief is avoided; this jihad is entirely reward. And the other is the jihad in which good wealth is not spent, there is no love for companions, the leader is disobeyed, and mischief is not avoided; this jihad is such that whoever participates in it, not only is reward unlikely, but even returning empty-handed is difficult.
