Respected Hakeem Sahab, Assalamoalaikum! I have two tested practices and hopefully, the readers of Ubqari will get benefit from them.
Before meeting any one recite کھٰیٰعص on fingers of right hand and close the hand and open when you reach infront of that person. He will do your related work without arguing and even if he is angry on you, he will meet you humble and will forget about any past issue.
For anger on yourself: If any one becomes angry on himself than whenever you eat or drink any thing blow this on water and drink. بِسْمِ اللہِ الرَّحْمٰنِ الرَّحِیْمِ یَاوَدُوْدُ
