Ibn Dorstawayh says that the word sidq refers to all praiseworthy qualities. Al–Khalil says sidq indicates complete perfection. In his Mufradat al–Qur’an, Ragib says, “Anything that is outwardly and inwardly agreeable is referred to as sidq, to which a qualified noun may be attached. Examples of Qur’anic Usage of the Word Sidq In the Holy Qur’an, we can find verses in which “ sidq ” is used as an adjective of things which are irrelevant to speech.

(54:55) e) “ It is not righteous that you turn your faces towards the East and the West, but righteous is this that one should believe in Allah and the Last Day and the angels and the Book and the Prophets, and give away wealth out of love for Him to the near of kin and the orphans and the needy and the wayfarer and the beggars and for ( the emancipation of ) the captives, and keep up prayers and pay the poor–rate; keep up their word when they make a promise, and the patient in distress and affliction and in time of conflicts – these are they who are true ( to themselves ) and these are they who are the truly god-fearing ” .

(2:177) In the above verse, God, the Mighty and High, first mentions righteousness of belief in God, the Last Day, the angels, the Divine Book and prophets. Then, He points to righteousness in practice including giving away one’s wealth, infak , to the relatives, the needy, the wayfarers, the beggars, or for the emancipation of captives for the sake of God, and keeping of promise.

He also refers to righteousness of morality, represented in patience in time of conflicts and endurance in time of hardships.
