﴿ لَّقَد تَّابَ ٱللَّهُ عَلَى ٱلنَّبِىِّ وَٱلْمُهَٰجِرِينَ وَٱلْأَنصَارِ ٱلَّذِينَ ٱتَّبَعُوهُ فِى سَاعَةِ ٱلْعُسْرَةِ مِنۢ بَعْدِ مَا كَادَ يَزِيغُ قُلُوبُ فَرِيقٍۢ مِّنْهُمْ ثُمَّ تَابَ عَلَيْهِمْ ۚ إِنَّهُۥ بِهِمْ رَءُوفٌۭ رَّحِيمٌۭ ﴾

“INDEED, God has turned in His mercy unto the Prophet, as well as unto those who have forsaken the domain of evil and those who have sheltered and succoured the Faiths - [all] those who followed him in the hour of distress, when the hearts of some of the other believers had well-nigh swerved from faith. And once again: He has turned unto them in His mercy - for, behold, He is compassionate towards them, a dispenser of grace.”

On the occasion of the battle of Tabuk, there was a group which surrendered its best asset to Islam: their crops. It was harvest time, but they left everything behind and set out on a journey which involved a march of three hundred miles in intense heat in order to face the most powerful empire of the time. The shortage of mounts, equipment and goods was so acute that several men had to take turns on each camel, and for food they had often to rest content with one date per person. However, they were only being tested for their resolve and dedication to the cause of God. After God had seen their mettle, He caused the enemy to fall a prey to terror. They retreated from the battlefield without any confrontation and the Muslims returned victorious without having shed any blood. There was another group which consisted of the confessors ( 9:102 ). These people could not set out on this journey due to their engagement in worldly activities. However, they very soon realised that they had made a serious mistake, to which they unreservedly confessed. They were truly ashamed of their misdeed and sincerely repented of it. The flood of tears flowing from their eyes compensated for their shortcomings. God enveloped them in His mercy, because they had admitted their mistake in all sincerity.
