And when He, the Exalted, mentioned their bliss in it, He mentioned their enjoyment in it and said: ﴿For them in it﴾ meaning in Paradise specifically, not in anything else ﴿is what they wish﴾ of all that their souls desire ﴿abiding﴾ they do not seek to change from it ﴿that was﴾ meaning all of that ﴿upon your Lord﴾ meaning the One who is good to you by being good to your followers ﴿a promise﴾.

And when He, glorified and exalted is He, indicated the obligation of that upon His great Self by the expression of "upon" and the promise, and since man is especially inclined to pride, he hardly allows himself to ask for what does not ensure its occurrence, He said: ﴿questioned﴾ meaning truly to ask for its fulfillment, because the one who asks is worthy to have his question answered, and his hopes and expectations realized. The meaning is that if it is added to His obligation of the thing upon Himself, the question of the promise made to him will certainly be fulfilled, and it is from the valley of ﴿I respond to the supplication of the supplicant when he calls upon Me﴾ [Al-Baqarah: 186]. And in it is a great encouragement to supplication, and a significant assurance of response, as He promised that, glorified and exalted is He, in ﴿I respond to the supplication of the supplicant﴾ [Al-Baqarah: 186] and ﴿Call upon Me; I will respond to you﴾ [Ghafir: 60]. And if the supplicant does not see the fulfillment, then the matter is as narrated by Imam Ahmad, Al-Bazzar, and Abu Ya'la Al-Mundhiri, with good chains - and Al-Hakim said: the chain is authentic from Abu Sa'id Al-Khudri, may Allah be pleased with him, that the Prophet, blessings and peace be upon him, said: "There is no Muslim who calls upon Allah with a supplication that does not contain sin or severing of kinship except that Allah will grant him one of three: either He will fulfill his supplication, or He will store it for him in the Hereafter, or He will divert from him an equivalent of it from evil." They said: Then we should increase? He said: Allah is more abundant.

And Al-Hakim narrated from Jabir, may Allah be pleased with him, from the Prophet, blessings and peace be upon him, that he said: "Allah will call the believer on the Day of Resurrection until He stands him before Him and says: My servant! I commanded you to call upon Me, and I promised you that I would respond to you. Did you call upon Me? He will say: Yes! O my Lord! He will say: Did you not call upon Me on such and such day for a distress that befell you, and I relieved you? He will say: Yes! O my Lord! He will say: Indeed, I hastened it for you in this world. And did you not call upon Me on such and such day for a distress that befell you, and you did not see relief? He will say: Yes! O my Lord! He will say: Indeed, I stored it for you in Paradise such and such. And did you not call upon Me for a need that I fulfilled for you on such and such day? He will say: Yes! O my Lord! He will say: Indeed, I hastened it for you in this world. And did you not call upon Me on such and such day for a need that I fulfilled for you, and you did not see its fulfillment? He will say: Yes! O my Lord! He will say: Indeed, I stored it for you in Paradise such and such. The Messenger of Allah, blessings and peace be upon him, said: So Allah will not leave any supplication made by His believing servant without clarifying for him either that He hastened it for him in this world or that He stored it for him in the Hereafter. The believer will then say in that position: I wish that nothing of his supplications had been hastened for him.

And Ibn Hibban in his Sahih and Al-Hakim said: The chain is authentic - from Anas, may Allah be pleased with him, who said: The Messenger of Allah, blessings and peace be upon him, said: "Do not be unable in supplication, for no one will perish with supplication."

And Al-Tirmidhi and Al-Hakim from Abu Huraira, may Allah be pleased with him, that the Prophet, blessings and peace be upon him, said: "Call upon Allah while you are certain of the response."

And in Al-Bukhari and Muslim (p-359) and Abu Dawood and Al-Tirmidhi and Ibn Majah from Abu Huraira, may Allah be pleased with him, that the Messenger of Allah, blessings and peace be upon him, said: "The supplication of any one of you is answered as long as he does not hasten, saying: I have called and have not been answered." And in a narration from Muslim and Al-Tirmidhi: "The servant will continue to be answered as long as he does not call for sin or severing of ties, as long as he does not hasten. It was said: O Messenger of Allah! What is hastening? He said: He says: I have called and have not been answered, and he becomes weary at that and leaves off supplication." Al-Mundhiri said: He becomes weary, meaning he gets tired and gives up on supplication - this has ended.

And it has been understood from the verse and the hadith in the exception of sin and severing of ties that what there is no barrier to asking for is promised to be answered and attained. So let a person supplicate for it, being certain of the response.
