۞ وَإِذِ ٱبْتَلَىٰٓ إِبْرَٰهِۦمَ رَبُّهُۥ بِكَلِمَٰتٍۢ فَأَتَمَّهُنَّ ۖ قَالَ إِنِّى جَاعِلُكَ لِلنَّاسِ إِمَامًۭا ۖ قَالَ وَمِن ذُرِّيَّتِى ۖ قَالَ لَا يَنَالُ عَهْدِى ٱلظَّٰلِمِينَ
And (remember) when his Lord tried Abraham with (His) commands, and he fulfilled them, He said: Lo! I have appointed thee a leader for mankind. (Abraham) said: And of my offspring (will there be leaders)? He said: My covenant includeth not wrong-doers.

Fasting
Chapter: To observe Saum (fast) or not during journeys
Narrated Ibn Abi `Aufa:
We were in the company of Allah's Messenger (ﷺ) on a journey. He said to a man, "Get down and mix Sawiq (powdered barley) with water for me." The man said, "The sun (has not set yet), O Allah's Messenger (ﷺ)." The Prophet (ﷺ) again said to him, "Get down and mix Sawiq with water for me." The man again said, "O Allah's Messenger (ﷺ)! The sun!" The Prophet (ﷺ) said to him (for the third time) "Get down and mix Sawiq with water for me." The man dismounted and mixed Sawiq with water for him. The Prophet (ﷺ) drank it and then beckoned with his hand (towards the East) and said, "When you see the night falling from this side, then a fasting person should break his fast."
