﴿ فَتَرَى ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌۭ يُسَٰرِعُونَ فِيهِمْ يَقُولُونَ نَخْشَىٰٓ أَن تُصِيبَنَا دَآئِرَةٌۭ ۚ فَعَسَى ٱللَّهُ أَن يَأْتِىَ بِٱلْفَتْحِ أَوْ أَمْرٍۢ مِّنْ عِندِهِۦ فَيُصْبِحُوا۟ عَلَىٰ مَآ أَسَرُّوا۟ فِىٓ أَنفُسِهِمْ نَٰدِمِينَ ﴾

“And yet thou canst see how those in whose hearts there is disease vie with one another for their good will, saying [to themselves], "We fear lest fortune turn against us." But God may well bring about good fortune [for the believers] or any [other] event of His own devising, whereupon those [waverers] will be smitten with remorse for the thoughts which they had secretly harboured within themselves-”

And you see those in whose hearts is sickness weakness of faith the like of ‘Abd Allāh b. Ubayy the hypocrite; vying with one another for them to affiliate with them saying as an excuse for this ‘We fear lest we suffer a turn of fortune’ which time will bring round against us such as drought or defeat and that if Muhammad’s affair should come to nothing they will cease to supply us with provisions. God exalted be He says But it may be that God will bring victory by assisting His Prophet and making His religion prevail; or some commandment from Him that will reveal the secrets of the hypocrites disgracing them; and then they will end up for what they kept secret within themselves in the way of doubt and affiliating with disbelievers remorseful.
