SHAFAQNA – Imam Hassan (AS) said: Piety is the beginning of any repentance, the summit of wisdom, the honour of any pious deed and the pious people have succeeded through piety . Therefore, when a person chooses to be pious he/she will remove all bad from himself/herself and start self-construction by truly worshipping Allah (SWT). In this regard, Imam Hassan (AS) explained: Whoever wants to worship Allah (SWT)Â just for the sake of worship, has purified himself/herself. Whenever recommended (Mostahabbat) prayers damage obligatory ones (Wajebaat), leave them .
