The Prayer of the Fasting Person Is Never Refused
From Thirty Lessons for those Who Fast

© Message Of Islam
Prophet Muhammad conveyed this in a well known saying: 'To the fasting person there is prayer that is never refused.' That is because the heart of the fasting person is repentant. He has subdued his stubbornness and checked his wild ambitions. Indeed, he has drawn closer to his Lord and obeyed Him. He abandoned his food and drink, fearful of the King, the Bestower. The fasting person has restrained his desires in obedience to the Lord of the heavens and the earth. The Prophet said: 'Supplication is worship.' Thus, if you see a servant begging a lot in prayer, know that he is close to Allah and confident in His Lord.
The companions once said to the Prophet: 'O Messenger of Allah, is our Lord near so that we may confide with Him secretly or is He far that we must cry out to Him?' Thereupon Allah Almighty revealed the following verse of the Quran: 'And if My servants ask thee about Me - behold, I am near; I respond to the call of him who calls, whenever he calls unto Me: let them, then respond unto Me, and believe in Me, so that they might follow the right way' (2:186).
In this same regard the Prophet said to his companions: 'You are not calling upon deaf or absent God. Verily you are calling upon a hearer and seer who is closer to any of you than the neck of his camel.' Supplication is an extended rope and solid divine bond. Hence the Prophet declared: 'No one will be destroyed with supplication.' For this reason Allah Most Merciful exhorts us to call upon Him: 'Call upon your Sustainer humbly, and in the secrecy of your hearts. Verily, He loves not those who transgressthe bounds of what is right' (7:55).
An: 'Call unto me Me, [and] I shall respond to you! Verily, they who are too proud to worship Me will enter hell, abased!' (40:60).
Still, the Prophet said: 'Our Lord descends to the heavens of the earth in the last third of the night and says: "Is there one who asks that I may grant him his request, is ther on who would call that I may answer him, and is ther one who seeks forgiveness that I may forgive him?'
Ramadan is the month of supplication, attainment, repentance and acceptance. O faster whose lips have dried from fasting, whose liver craved for thirst, and whose stomach hungered; call upon your Lord in earnest and be insistent in your request. Remember Allah's description of His servants: 'They would vie with one another in doing good works, and would call unto Us in yearning and awe; and they were always humble before Us' (21:90).
There are certains ethics of supplication that the fasting person should know. They include: the resolcve of the heart and full trust in generosity and favour of Allah. The Prophet said: 'None of you should say, "O my Lord fogive me if You will." He should instead be insistent in his asking because nothing forces Allah.' Among these ethics also is that the servant should praise Allah and send greetings upon his noble Messenger at the beginning, in the middle and at the end of his supplication. The believer should be concious of the times when prayers are answered such as the last third of the night, while prostrating, between the call to prayer (Azaan) and its commencement (Iqamah) , at the end of the compulsory prayers, the last hour of Friday (Yaum-ul-Jum'uah) , after Asr Prayer, and on the day of Arafat . The believer must avoid rhymed prose in supplication, assigning someone to do it, or excesses in it. One should be careful not to invoke sin or the cutting of kindred ties.
O You who fast, know that the inal hour before the setting of the sun is one of the greatest hours of the day. Before the breaking of the fast when hunger has become acute and your thirst most intense, make much supplication, increase your yearning and continue to ask. Note that there is also ans hour before daybreak for you who fast. Therefore, be good to yourself and ask from the Ever-Living the Self-Subsisting because you are poor and He is rich, you are weak and He is strong, you will pass away and He will remain.
The Prophet Abraham prayed: 'O my sustainer, cause me and [some] of my offspring to remain constant in prayer! And, O our Sustainer, accept this my prayer: grant Thy forgiveness unto me, and my parentsm and all the believers, on the Day on which the [last] reckoning will come to pass!' (14:40-1).
Prophet Moses prayed: 'O my sustainer! Open up my heart [to thy light], and make my task easy for me' (20:25).
Prophet Solomon called upon his Lord and asked: 'O my Sustainer! Forgive my sins, and bestow upon me the gift of a kingdom which may not suit anyone after me: verily, Thou aone art a giver of gifts!' (38:35).
In an authentic hadith the Prophet Muhammad prayed: 'O my sustainer! You are the Lord of Gabriel, Mika'il and Israfil. You are the maker of the heavens and the earth. You judge between Your servants in what the differ. Guide me to the truth by Your permission. For you guide whomsoever You will to the straight path.'
There are four advantages to supplication:
First: the realization of worship of Allah Almighty, humbleness towards Him and trust in Him. This is the purpose and fruit of worship.
Second: the answering of one's request either through the granting of good or by the prevention of harm. None other than Allah possesses this power and ability.
Third: to save the reward with Allah if the request is not granted in this world. This is actually better and more beneficial.
Fourth: supplication expresses sincere monotheism through the crushing of dependency on people and yearning for their favour.
O our Lord! Grant us good in this world and good in the Hereafter and save us from the punishment of the fire. O our Lord! Do not cause our hearts to go astry after you have guided and grant us mercy from Yourself. Verily You are the Donor of all good.
