1. Taqwa is a means by which a believer performs righteous deeds and Taqwa, causes the righteous deed to be accepted by Allah.

Allah says: “O you who believe! Have Taqwa (fear) of Allah and always speak the truth. He will direct you to do righteous and correct actions and will forgive you your sins and whoever obeys Allah and His Messenger has
indeed attained a great achievement.” [Soorah al-Ahzaab (33): 70]

and: “Verily Allah accepts only from those who are the muttaqoon (those who posses Taqwa).” [Soorah al-Maaidah (19): 71-72]

2. Taqwa makes one deserving of Allah’s Pleasure and Love. Allah says: “Verily, the most honorable of you in the Sight of Allah is that (believer) who has Taqwa.” [Soorah al-Hujurat (49): 13]

and: “Whoever fulfills his pledge and has Taqwa of Allah much, then indeed, Allah loves those who are muttaqoon (those who posses Taqwa).” [Soorah Aal-Imraan (3): 76]

3. Taqwa causes sins to be forgiven and increases rewards. Allah says: “And whoever fears Allah and keeps his duty to Him. He will remit his sins from him, and will enlarge his rewards.” [Soorah at-Talaaq (65): 5]

4. Taqwa keeps one steadfast on the Straight Path and protects him from deviation.

Allah says: “O you who believe! Have Taqwa of Allah. He will give you a Furqaan (criterion to judge between right and wrong).” [Soorah al-Anfaal (8): 29]

Imaam Ibn al-Katheer (rahimahulla) said in his Tafseer, ‘Ibn Abbas, as-Sudde, Ikrimah, adh-Dahhak, Qataadah and Muqaatil, Ibn Huyyan, all said about ‘Furqaan’ that it means a way out (from difficulty).

Mujaahid added: ‘A way out from difficulty both in this world and in the Hereafter.’ In a narration from Ibn Abbas, he said: “It means, ‘Salvation’ and in another narration from him ‘being helped.’ Muhammad Ishaaq said that it means: ‘A criterion to judge between truth and falsehood.’ This explanation from Ibn Ishaaq is the most general of what has proceeded and it is a necessary consequence of it. Since whoever has Taqwa of Allah by obeying His commands and abandoning what He has prohibited, will be given the ability to recognize truth from falsehood.
