A very interesting point to note is that in Du’a Makarim al Akhlaq, (Du’a 20 of Sahifa Sajjadiyya), Imam al-Sajjad (a) recites salawaat after every few verses. This shows us that if we want to improve our akhlaq, we must learn from the Holy Prophet (saww).
Imam Ali (a) is reported to have said, "Verily the friends of Allah are those who remember Him the most, are constantly grateful to Him and have greater patience in the face of His trials."
