وَإِذْ أَخَذْنَا مِيثَٰقَكُمْ وَرَفَعْنَا فَوْقَكُمُ ٱلطُّورَ خُذُوا۟ مَآ ءَاتَيْنَٰكُم بِقُوَّةٍۢ وَٱذْكُرُوا۟ مَا فِيهِ لَعَلَّكُمْ تَتَّقُونَ
And (remember, O Children of Israel) when We made a covenant with you and caused the mount to tower above you, (saying): Hold fast that which We have given you, and remember that which is therein, that ye may ward off (evil).

Sahih al-Bukhari
Call to Prayers (Adhaan)
Chapter: To stand on the right side of the Imam on the same line if only two persons (counting the Imam) are offering Salat (prayer) in congregation
Narrated Ibn `Abbas:
Once I passed the night in the house of my aunt Maimuna. Allah's Messenger (ﷺ) offered the `Isha' prayer and then came to the house and offered four rak`at an slept. Later on, he woke up and stood for the prayer and I stood on his left side. He drew me to his right and prayed five rak`at and then two. He then slept till I heard him snoring (or heard his breath sounds). Afterwards he went out for the morning prayer.
