Allahumma salli wa sallim `alaa Sayyidina wa Mawlana Muhammadin `adada maa fee `ilmillahi salaatan daa’imatan bi-dawaami mulkillah.
From the book Afdal as-Salawaat by Shaykh Ahmad as-Saawee is said if you read this salawat once, it is rewarded as if you said salawaat 600,000 times and if you recite it seventy times a day you will be released from Hellfire! O Allah! Exalt and send peace on our Leader and Master Muhammad on the number of what exists in Allah’s Knowledge with ongoing prayers as long as Allah’s Kingdom exists.
Mawlana Shaykh Hisham said,
"If you cannot recite (them all) say, yaa rabbee nawayna mithla maa nawa Mawlana Shaykh, "O Allah! As Mawlana Shaykh made intention we are making the same intention!" and it will be as if you have read all of them. That is the easiest way, to say, "As Mawlana made intention, we do the same intention," and that is the way of awliyaullah!
