۞ مَّآ أَشْهَدتُّهُمْ خَلْقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَلَا خَلْقَ أَنفُسِهِمْ وَمَا كُنتُ مُتَّخِذَ ٱلْمُضِلِّينَ عَضُدًۭا
I made them not to witness the creation of the heavens and the earth, nor their own creation; nor choose I misleaders for (My) helpers.

Chapter: What is said about Zamzam (water)
Narrated Ibn `Abbas:
I gave Zamzam water to Allah's Messenger (ﷺ) and he drank it while standing. `Asim (a sub-narrator) said that `Ikrima took the oath that on that day the Prophet (ﷺ) had not been standing but riding a camel.
