It was said in Tuhfa Arridawiyah: you should send salawat to the Prophet (saw) 100 times after the recommended nafilah after the Maghrib Prayer and then recite the following 70 times. After this you recite salwat again 100 times and forward your requests.
Sayyid Allamah al Wahid mentioned that it was tested for achieving important issues.
O’ Allah, O’ Muhammad, O’ Ali, O’ Fatimah, O’Al-Hassan, O’ Al-Hussain, O’ the leader of the time, come to my aid, O’ the leader of the time.
