وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ٱلْقُرْءَانُ جُمْلَةًۭ وَٰحِدَةًۭ ۚ كَذَٰلِكَ لِنُثَبِّتَ بِهِۦ فُؤَادَكَ ۖ وَرَتَّلْنَٰهُ تَرْتِيلًۭا
And those who disbelieve say: Why is the Qur'an not revealed unto him all at once? (It is revealed) thus that We may strengthen thy heart therewith; and We have arranged it in right order.

Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: If the people get frightened at night
Narrated Anas:
Allah's Messenger (ﷺ) was the (most handsome), most generous and the bravest of all the people. Once the people of Medina got frightened having heard an uproar at night. So, the Prophet (ﷺ) met the people while he was riding an unsaddled horse belonging to Abu Talha and carrying his sword (slung over his shoulder). He said (to them), "Don't get scared, don't get scared." Then he added, "I found it (i.e the horse) very fast."
