Allahumma salli `ala Muhammadin wa `ala aali Muhammadin wa sallim.
Grandshaykh قدس سرّه said that if you are unable to recite Dala’il al-Khayrat as part of your daily wird, then recite this salawat 100 times, which is the easiest and simplest form of salawat on the Prophet , as it shows the humility of the Prophet towards His Lord.
O Allah! Send blessings and peace upon Muhammad and the Family of Muhammad.
