﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ مَا لَكُمْ إِذَا قِيلَ لَكُمُ ٱنفِرُوا۟ فِى سَبِيلِ ٱللَّهِ ٱثَّاقَلْتُمْ إِلَى ٱلْأَرْضِ ۚ أَرَضِيتُم بِٱلْحَيَوٰةِ ٱلدُّنْيَا مِنَ ٱلْءَاخِرَةِ ۚ فَمَا مَتَٰعُ ٱلْحَيَوٰةِ ٱلدُّنْيَا فِى ٱلْءَاخِرَةِ إِلَّا قَلِيلٌ ﴾

“O YOU who have attained to faith! What is amiss with you that, when you are called upon, "Go forth to war in God's cause," you cling heavily to the earth? Would you content yourselves with [the comforts of] this worldly life in preference to [the good of] the life to come? But the enjoyment of life in this world is but a paltry thing when compared with the life to come!”

These verses were revealed while the Prophet was at Tabuk (9 Hijra). At this juncture the behaviour displayed by the hypocrites (munafiqun) of Madinah gives us an idea of the role played by people of fickle faith when they join the Islamic society. In reality there are two stages of connection with Islam. In one, all of man’s loyalties become attached to Islam; it becomes a question of life and death for him. In the other, man’s real interests are elsewhere and he only superficially accepts Islam. In the first category are the real believers—the people of faith. In the second are those known, in the terminology of the Shariah, as munafiq (hypocrites). The condition of the believer is that he steadfastly holds to Islam in normal circumstances as well as at times when sacrifice is required. By contrast, the hypocrite seems to be very much to the fore in making a show of his religiousness, when Islam makes no special demands on him, but as soon as he has to fulfil demands of Islam at the level of sacrifice, he backs away.
