Surah At-Taubah, Ayat 81

Ayat 81. Those who stayed away (from Tabuk expedition) rejoiced in their staying behind the Messenger of Allah  [SAWW](PBUH). ; they hated to strive and fight with their properties and their lives in the Cause of Allah, and they said: "March not forth in the heat." Say: "The Fire of Hell is more intense in heat", if only they could understand!  

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "He who dies without having fought in the Cause of Allah or without having thought of doing so, will die with one characteristic of hypocrisy in him.'' [Muslim Hadith # 1910].   

Lesson : as mentioned above in Surah At-Taubah Ayat.81."They hated to strive and fight with their properties and their lives in the Cause of Allah" We learn from this Hadith that it is a different matter that one may not get a chance to take part in Jihad, but it would be a hypocritical attitude if one does not ever think that if an opportunity ever comes in his way, he will certainly go for Jihad in the way of Allah against the infidels. The reason to that is that, to stay back at home at the time of Jihad was a habit of the hypocrites. In the light of this, Imam Al-Qurtubi has stated the principle that if one is not capable of doing some virtuous deeds, he should then make a resolve that whenever he will be capable of it, he will do that deed, so that his intention takes the place of his act. He who neither performs a good deed nor aspires for it, has a hypocritical disposition. This is specially true of a Muslim who does not even aspire to take part in Jihad. Such a Muslim develops a resemblance with hypocrites.
