خَٰشِعَةً أَبْصَٰرُهُمْ تَرْهَقُهُمْ ذِلَّةٌۭ ۖ وَقَدْ كَانُوا۟ يُدْعَوْنَ إِلَى ٱلسُّجُودِ وَهُمْ سَٰلِمُونَ
With eyes downcast, abasement stupefying them. And they had been summoned to prostrate themselves while they were yet unhurt.

Chapter: Superiority of (praying) facing the Qiblah with the toes toward it as well
Narrated Anas bin Malik:
Allah's Messenger (ﷺ) said, "Whoever prays like us and faces our Qibla and eats our slaughtered animals is a Muslim and is under Allah's and His Apostle's protection. So do not betray Allah by betraying those who are in His protection."
