From Sa`eed ibn Mu’adh, it is narrated that he said: “Never have I prayed a Salah in which I spoke to myself about the affairs of this world, until I left the mosque.”
And it is reported from Abu ad-Darda’ that he said: “My face be covered in dust for my Lord (is most loved by me), — for that is the best kind of worship from Allaah.”
So let none of you fear the dust, nor find it distasteful to make sujood in it, for there is no doubt that every one of you comes from it (i.e. mankind was created from dust). Nor should any of you fear an excess of it, for verily, it is by this means that one attempts to attain freedom from slavery and salvation from the Hell-fire — a fire before which the fixed, lofty mountains which were placed as pegs (holding the earth) could not stand, nor the seven strong heavens, built one above another, which are placed as a well guarded canopy over us, nor the earth, which was placed as a dwelling for us, nor the seven seas, of which none knows their depths or their size except the One Who created them. Then what about us, with our feeble bodies, our delicate bones, our flimsy skin? We seek refuge with Allaah from the Fire!
So should any of you stand in Salah — may Allaah have mercy on you, then let him be as if he sees Allaah before him, for though he may not see Allah, verily, Allaah sees him. It is narrated in a hadith that Allaah’s Messenger advised a man, saying: «Fear Allaah as though you see Him, for verily, though you may not see Him, He sees you.»
This then, is the advice of the Prophet to the slave in all his affairs, so what about when he performs Salah, when he stands before Allaah, in a particular place, a sacred place, desiring Allaah and turning his face towards Him? Does not his standing, his situation in Salah merit the same ihsan as all his affairs?
It says in a hadeeth: «Verily, the slave, when he starts his Salah, should turn his face to Allaah, and he should not turn it away from Him until he leaves or turns to right and left.» [Ahmad, Abu Dawood and Nasa’i]
It is also narrated in a hadeeth: «Verily, the slave, as long as he is in Salah, possesses three qualities. Blessings are showered upon his head from the heavens above, the angels sit around him, from his feet to the heavens and a caller says, “If the slave knew the One Who hears his whispered utterances, he would never leave his Salah.” » [This narration is mentioned by Muhammad ibn Nasr al-Mirwazi in Kitab as-Salah — The Book of Prayer from the hadeeth of Hasan al-Basri in a mursal form.]
Allaah showers His Mercy upon the worshipper who approaches prayer in a state of humility and meekness towards Allaah, in fear and supplicating Him with desire (for His Pleasure) and in hope (of His Mercy), making Salah to his Lord, his most important consideration, dedicating his whispered utterances to Him and his standing erect in worship and his rukoo` and his sujood, poring out his heart and his feelings and struggling to perfect his acts of worship, for he knows not whether he will perform another prayer after it, or he will be overtaken (by death) before he can perform Salah again. He stands before his Lord, earnestly, with deep feelings, hoping for its acceptance and fearing its rejection, for verily, its acceptance is a cause for joy, while its rejection is a cause for misery and wretchedness. Nothing could be more important to you — O’ my brother — in this Salah, or indeed in any of your actions (i.e. that Allaah should accept them). What is more deserving of your distress and misery, your fear — indeed your terror — you know not whether your Salah will find favour with Allaah at all, nor whether any of your good deeds will be accepted. Do you know if your sins will be forgiven at all? After all this, you have no assurance that you will be spared from it (i.e. the punishment of the Hell-fire). So who is more deserving of your tears and sadness (than Allaah) — that He may accept from you (your deeds)?
In addition to this, you know not whether or not you will awaken in the morning, nor if you will still be here in the evening — will you be given the good news of Paradise, or the bad news of the Hell-fire? I only desire to warn you — O’ my brother — of this terrible danger. It is not fitting that you should be happy because of your family, your wealth or your children. It is a most amazing thing that you should continue to be unmindful, chasing after vain desires, wasting your time in disregard of this most important matter, for you are being driven at a fierce pace (towards death) day and night, hour by hour, like the blink of an eye. You should expect — O’ my brother — that your time may come at any moment and do not be unmindful of this great danger which may visit you. Most assuredly, you must (eventually) taste death. Your time may come in the morning or in the evening. You will be separated from all that you possessed — either (to be rewarded with) Paradise or (to be punished in) the Hell-fire. Descriptions and stories of them (have become) superfluous. Have you not heard — O’ my brother the words of the pious slave: “I am amazed concerning the Hell-fire — how does the one who would flee from it sleep? And I am amazed concerning the Jannah — how does the one who desires it sleep? For by Allaah! If you neither desire Paradise, nor fear the Hell-fire, then you are destroyed and grievous will be your sorrow, interminable your sadness and without limit your tears; you will be amongst the wretched, the punished ones. So if you claim that you are amongst those who seek refuge from the Fire and desire Paradise, then strive for that which you seek and do not be misled by your worldly desires.” Know — may Allaah have mercy on you — that Islam is in retreat, knowledge is decreasing, disappearing; it is narrated in a hadeeth from the Prophet that he said: «Islam began with only a few followers, and it will again be as it was when it began.» [Muslim and Tirmidhi]
