On the authority of ʿAbdullāh b. Masʿūd (may Allāh be pleased with him) the Prophet (praise and security of Allāh be upon him) would supplicate saying:
“Oh Allāh, I ask from you guidance, piety, purity and sufficiency”.
Reported by Muslim[i]
This supplication is one of the most comprehensive and beneficial of supplications. It is asking for all good associated with a person’s religion as well as the good associated with his worldly life.
Guidance is beneficial knowledge while piety is doing righteous deeds and abstaining from all that Allāh and His Messenger have prohibited. With this, a person’s religious life becomes right as the religion comprises of beneficial knowledge, as true insights are guidance, while obedience to Allāh and His Messenger is piety.
Purity is to be pure of others by not attaching the heart to them. Sufficiency is with Allāh and the sustenance He provides while finding contentment therein. It is to attain enough to find tranquility of the heart. With this a person attains happiness in this world and serenity of the heart, which is “al-Ḥayāt al-Ṭayyibah” a good life.
Whoever is given guidance, piety, purity and sufficiency has attained happiness in both worlds and everything he could ask for. He has also been saved from everything he would dread.
And Allāh knows best.
