Shaykh Dr. Yasir Qadhi gives a lecture on some verses of Surah az-Zumar and acquaints us with the blessings of Islam.
"So is one whose breast Allah has expanded to [accept] Islam and he is upon a light from his Lord [like one whose heart rejects it]? Then woe to those whose hearts are hardened against the remembrance of Allah. Those are in manifest error.” Allah has sent down the best statement: a consistent Book wherein is reiteration. The skins shiver therefrom of those who fear their Lord; then their skins and their hearts relax at the remembrance of Allah. That is the guidance of Allah by which He guides whom He wills. And one whom Allah leaves astray - for him there is no guide."
[Surat Az-Zumar, verses 22 & 23]
"Allah takes the souls at the time of their death, and those that do not die [He takes] during their sleep. Then He keeps those for which He has decreed death and releases the others for a specified term. Indeed in that are signs for a people who give thought."
[Surat Az-Zumar, verse 42]
"O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah . Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful. And return [in repentance] to your Lord and submit to Him before the punishment comes upon you; then you will not be helped."
[Surat Az-Zumar, verses 53 & 54]
This verse is the most hopeful and optimistic verses in the entire Qur'an.
From the above verses, we can learn many aspects of our life:
Some of us have no love for Islam as our hearts have been hardened by the worldly pleasures and true Iman evades us.
The greatness of the Qur'an is explained in vivid detail.
The hearts of the believer tremble when they hear the Qur'an sometimes and sometimes as you read it , the heart finds comfort and peace.
We are made to be optimistic of the Mercy of Allah as He forgives all our sins. This can be achieved by turning in repentance towards Allah.
