Moreover, the sacred meaning of the second and third ayats (verses) in Sura (chapter) Saff: “Believers! Why do you profess what you never did? Allah dislikes you when you say something you cannot practice,” shows that a person’s vowing or promising what he cannot perform makes him a bad person in Allahu ta’ala’s view.
A true Muslim is extremely respectful to his parents, teachers, commanders, the laws, and to the leading authorities of his country. He is not concerned with something insignificant. He is busy only with something useful. He doesn’t gamble. He doesn’t kill his time.
A true Muslim does his worships perfectly. He offers gratitude to Allahu ta’ala. Worship should not be performed unwillingly or unconsciously. Worship must be performed willingly and with great love for Allahu ta’ala. To fear Allahu ta’ala means to love Him very much. You do not want the person you love much to be displeased and you are afraid lest you might cause him to be disturbed. In this way, worship for Allahu ta’ala should be performed in such a manner as to prove our love for Him. The blessings which Allahu ta’ala has given us are so great that our debt of gratitude to Him can be paid only by loving Him much and by worshipping Him with profound sincerity. There are different kinds of worship. Some kinds of worship, as we have said above, are between Allahu ta’ala and His slave. Maybe Allahu ta’ala will forgive those who worship insufficiently. It is worship to respect others’ rights, too. But He will never forgive those who abused others and have the rights of others’ on them, unless the owners of those rights forgive them.
