Shaykh Muhammad ibn Sālih al ‘Uthaymīn (rahimahullāh) said,
The wisdom behind fasting is not that a person merely prevents himself from the grace of Allāh (‘azza wa jal), such as food, drink and sexual relations; however the wisdom behind fasting is something greater than that, it is (that you attain) the taqwa of Allāh, as Allāh (tabāraka wa ta’āla) said when he mentioned the obligation of fasting
[البقرة:183] { لَعَلَّكُمْ تَتَّقُونَ }
That you may become al-Muttaqūn [the pious and righteous persons who fear Allah much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Allah much (perform all kinds of good deeds which He has ordained)]. Al-Baqarah: 183
The taqwa of Allāh is to obey Him, adhere to His commandments and abstain from His prohibitions.
The meaning of taqwa, is that the servant places a barrier between him and between that which he fears. And the taqwa of a servant in relation to his Lord, is that he places between him and his Lord a barrier that protects him from that which he is scared of, from Allah’s anger, displeasure and punishment.
And that is not achieved except by the performance of acts of obedience and refraining from acts of disobedience.
Allah (Subhānahu wa ta’āla) began this great sūrah (Suratul Mulk) with praise and glorification of Himself, and He is the most deserving to be praised and glorified.
The meaning of تبارك (tabāraka) is تعاظم. Allāh is the one who, when performing dhikr of him, blessings are obtained from (when done sincerely for Allāh and in accordance with the sunnah of the Messenger of Allah (sallallāhu alaihi wa salam)). He is the one who sends down blessings and He is the one who bestows blessings on whomsoever He wills.
This word ‘tabāraka’ does not apply except when speaking of Allāh, hence it is not allowed to say to someone “Oh so and so, tabārak upon us”, as some of the ignoramuses say.
However, as for saying to someone, you are “mubārak”, then there is no issue with it, because the meaning of “mubārak” is that Allāh (Subhānahu wa ta’āla) has blessed you and bestowed his blessings upon you.
Allāh (Subhānahu wa ta’āla) said:
وَجَعَلَنِي مُبَارَكًا أَيْنَ مَا كُنتُ
“And He has made me blessed wheresoever I be (Sūrah Maryam: 31) and
كِتَابٌ أَنزَلْنَاهُ إِلَيْكَ مُبَارَكٌ
(This is) a Book (the Qur’ān) which We have sent down to you, full of blessings (Sūrah Sād: 29).
Therefore, Allāh is the one who bestows blessings and places blessings in whoever, wherever and whatsoever he wills. As for mankind, they can not bless themselves, indeed it is only Allāh who gives mankind blessings and makes them blessed.
Slightly Paraphrased from Shaykh Sālih al-Fawzān’s ‘Mā Tayassara wa Tahassala min Durūs al-Qurān fī Hizb al-Mufassal’ Vol.2 Page 6
(And remember) when Allāh took a covenant from those who were given the Scripture (Jews and Christians) to make it (the news of the coming of Prophet Muhammad (sallallāhu alaihi wa salam) and the religious knowledge) known and clear to mankind, and not to hide it, but they threw it away behind their backs, and purchased with it some miserable gain! And indeed worst is that which they bought. ((Aali Imrān:187)
Verily, those who purchase a small gain at the cost of Allāh’s Covenant and their oaths, they shall have no portion in the Hereafter (Paradise). Neither will Allāh speak to them, nor look at them on the Day of Resurrection, nor will He purify them, and they shall have a painful torment. (Aali Imrān: 77)
Allah has censured the People of the Book (Jews and Christians) due to their turning away and abandoning their revealed books; likewise they have been censured for devoting themselves (primarily) to (attaining the pleasures of) the worldly life and preoccupying themselves with other than what they have been commanded with – following the revelation (which was revealed to them).
So upon us, oh Muslims, is to refrain from those (aforementioned) affairs which caused Allāh to censure the People of the Book.
We should fulfil that which we have been commanded with. We should (pay attention and give concern to) studying the Book of Allāh, (which was revealed to us) teach it, understand it and teach its understanding (to others), Allāh said:
Has not the time come for the hearts of those who believe (in the Oneness of Allāh – Islamic Monotheism) to be affected by Allāh’s Reminder (this Quran), and that which has been revealed of the truth, lest they become as those who received the Scripture [the Taurat (Torah) and the Injīl (Gospel)] before (i.e. Jews and Christians), and the term was prolonged for them and so their hearts were hardened? And many of them were Fāsiqun (rebellious, disobedient to Allāh). [Al-Hadīd:16]
