One prayer of blessing upon the Prophet

الصلاة على النبي مرة واحدة

Whoever invokes one blessing upon the Prophet ﷺ, God blesses him ten times, ten sins are shed from him and he is raised ten ranks, in Anas's narration in al-Nasa'i Sunan al-Nasa'i 1297 — ranks raised; bad deeds erased and sins shed; the core of ten for one is in Muslim Muslim 384 — Whoever sends one prayer on me, God sends ten; ask for me the wasila. One act here moves three columns at once: the blessings, the erasure and the ranks.
