As-salaamu `alayka ayyuhan-nabiyyu wa rahmatullahi wa barakaatuh.
The Prophet said that anyone who reads this salawat once every day will not feel sakharaat al-mawt, the pain of death, and his soul will go smoothly, as the hadith mentions that the soul of the mu`min will leave the body like a hair being pulled from ghee, so easily. So recite the above mentioned salawat together with the recitation of the Jawharat al-Kamaal at least once daily.
O Prophet! Allah's peace, blessings and grace be upon you.
