When one reflects upon the beauty of the religion of Islām, they will come to realise with certainty that it contains a cure for the illnesses of the heart, body, mind, and soul. Alhamdulillāh for Islām!
A believer calls upon Allāh with complete certainty that their du'ā will be answered. Why? Because they believe with certainty of Allāh's generosity, knowing that He never lets down those who turn to Him sincerely, calling upon Him directly and alone with an attentive heart.
Refuting falsehood is from our religion,rather it is one of the greatest of obligations,as it is the key for preservation of the religion. Don't be deceived by those who say: "stop talking about Shirk&Bida'ah." If only they knew the dire consequences of their erroneous statement.
