O son, when you find yourself being temperamental for no apparent reason, know that you have not been doing enough salawat to cool your body down. This one is especially good for a heated body. May I remind you that whatever little thing I post for you here is not to show you that I know it all. More often than not, it reflects what I have just learned or what I need at the moment.
Allahuma salli 'ala Muhammad
Allahumma salli 'alaihi wasallim
May Allah bless Shaykh Fahmi Zamzam for his fatherly counsel and all the useful du'as and wirids taught in a pocket book loaded with great compilations - "Bekal Akhirat".
