غزوة تبوك
The Battle of Tabuk
Rajab, 9 AH (630 CE)
Tabuk, northern Arabia
Learning that the Byzantine Empire was gathering forces near the northern border, the Prophet ﷺ mobilized the largest army in Islamic history — 30,000 warriors — and marched to Tabuk in extreme heat and drought. The expedition was called 'Jaysh al-Usrah' (the Army of Hardship). Uthman ibn Affan single-handedly funded a large portion of the expedition. When they reached Tabuk, the Byzantine forces had withdrawn, and the Prophet ﷺ secured the northern frontier through treaties with local tribes.
Why this matters
Tabuk was the final major military expedition of the Prophet ﷺ. It exposed the hypocrites who made excuses not to participate, and Surah At-Tawbah was largely revealed in this context. The story of Ka'b ibn Malik, who truthfully confessed his failure to join and was boycotted for fifty days before Allah accepted his repentance, is one of the most powerful narratives in the hadith literature.

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 إِلَّا تَنفِرُوا۟ يُعَذِّبْكُمْ عَذَابًا أَلِيمًۭا وَيَسْتَبْدِلْ قَوْمًا غَيْرَكُمْ وَلَا تَضُرُّوهُ شَيْـًۭٔا ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌ
Surah At-Tawbah, 38-39
O you who have believed, what is [the matter] with you that, when you are told to go forth in the cause of Allah, you adhere heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But what is the enjoyment of worldly life compared to the Hereafter except a [very] little. If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent.
وَعَلَى ٱلثَّلَٰثَةِ ٱلَّذِينَ خُلِّفُوا۟ حَتَّىٰٓ إِذَا ضَاقَتْ عَلَيْهِمُ ٱلْأَرْضُ بِمَا رَحُبَتْ وَضَاقَتْ عَلَيْهِمْ أَنفُسُهُمْ وَظَنُّوٓا۟ أَن لَّا مَلْجَأَ مِنَ ٱللَّهِ إِلَّآ إِلَيْهِ ثُمَّ تَابَ عَلَيْهِمْ لِيَتُوبُوٓا۟ ۚ إِنَّ ٱللَّهَ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ
Surah At-Tawbah, 118
And [He also forgave] the three who were left behind [and regretted their error] to the point that the earth closed in on them in spite of its vastness and their souls confined them and they were certain that there is no refuge from Allah except in Him. Then He turned to them so they could repent. Indeed, Allah is the Accepting of repentance, the Merciful.
