[Pooya/Ali Commentary 38:31] Aqa Mahdi Puya says: While inspecting his thorough bred (khayr) horses Sulayman realised that the sun had set. Dhikr does not refer to compulsory prayers, because a prophet would not be forgetful of such prayers. It should therefore be normal remembrance of Allah. Some commentators say an (in verse 32) means "due to" or "with a view to" because the horses were purchased for jihad in the cause of Allah. In verse 33 mas-ha means "to rub" or "to pass hand over". Like all lovers of horses, and particularly because they were to be used in the cause of Allah, he patted them on their necks and passed his hand over their forelegs and was satisfied with having them, not as vanities but as a lover of good (khayr). His review of horses was interrupted by his evening devotion, but he resumed it after performing his devotion.
