"The Messenger of Allah ﷺ said: "Whoever sends salah upon me once, Allah (SWT) will send salah upon him tenfold, and will erase ten sins from him, and will raise him ten degrees in status." (Using translation from Nasāʾī 1297)
قَالَ رَسُولُ اللهِ ﷺ «مَنْ صَلَّى عَلَيَّ صَلَاةً وَاحِدَةً صَلَّى الله عَلَيْهِ عَشْرَ صَلَوَاتٍ وَحُطَّتْ عَنْهُ عَشْرُ خَطِيئَاتٍ وَرُفِعَتْ لَهُ عَشْرُ دَرَجَاتٍ»
