The Virtue of Reading Sholawat
In the Indonesian dictionary, the word shalawat is the plural of prayer which means 'request to Allah' or 'prayer: praying for God's blessings' or 'praying to Allah for the Prophet Muhammad SAW and his family and companions'
Shalawat for the people of Muhammad SAW towards him is acknowledging his apostleship as well
Ask for intercession and get closer to Allah SWT
So the acknowledgment of the apostleship of Muhammad SAW is not only pledged by saying the shahada.
