Al-Bukhari sifted some six hundred thousand narrations over sixteen years, praying two units of prayer before entering each report. What survived his sieve became the second most consulted book in Islam, and its chapters on the salutation preserve the exact words the Companions asked for and were given.
مَنْ صَلَّى عَلَيَّ صَلَاةً صَلَّى اللَّهُ عَلَيْهِ بِهَا عَشْرًا
Man ṣallā 'alayya ṣalātan ṣallā Allāhu 'alayhi bihā 'ashrā
Whoever sends one blessing upon me, Allah sends ten blessings upon him in return.
Reported in Sahih Muslim; the exchange of light, tenfold
None of you truly believes until I am more beloved to him than his father, his child, and all of mankind.
Sahih al-Bukhari 15
