He who is amongst those who pray will be called from the gate of the prayer (in Paradise) and he who is from the people of Jihad will be called from the gate of Jihad, and he who is from those' who give in charity (i.e. Zakat) will be called from the gate of charity, and he who is amongst those who observe fast will be called from the gate of fasting, the gate of Raiyan." Abu Bakr said, "He who is called from all those gates will need nothing," He added, "Will anyone be called from all those gates, O Allah's Apostle?" He said, "Yes, and I hope you will be among those, O Abu Bakr." [Bukhari]
Abu Hurairah reported that the Prophet (S) said : "The time between the five prayers, two consecutive Friday Prayers, and two cosecutive Ramadans are expiations for all that has happened during that period, provided that one has avoided the grave (major) sins." [Muslim]
In another hadith, the Messenger of Allah (may Allah bless him and grant him peace) says, "Ramadan has come to you. (It is) a month of blessing, in which Allah covers you with blessing, for He sends down Mercy, decreases sins and answers prayers. In it, Allah looks at your competition (in good deeds), and boasts about you to His angels. So show Allah goodness from yourselves, for the unfortunate one is he who is deprived in (this month) of the mercy of Allah, the Mighty, the Exalted." [Narrated by Tabarani]
Abu Umaamah r.a.a. said: I said: 'O Messenger of Allah, tell me of an action by which I may enter Paradise'. He said: 'Take to Fasting, there is nothing like it.' [An-Nasaa'ee, Ibn Hibbaan, Al-Haakim, Saheeh]
"Fasting is prescribed for you as it was prescribed for those before you, that you may attain taqwaa." [2:183]
The most honoured by Allah amongst you are those best in taqwaa."[49:13]
"Every action of the son of Adam is given manifold reward, each good deed receiving then times its like, up to seven hundred times. Allah the Most High said, 'Except for fasting, for it is for Me and I will give recompense for it, he leaves off his desires and his food for Me.' for the fasting person there are two times of joy; a time when he breaks his fast and a time of joy when he meets his Lord, and the smell coming from the mouth of the fasting person is better with Allah than the smell of musk." [al-Bukhaaree]
"Fasting is a shield with which a servant protects himself from the Fire." [Ahmad, Saheeh]
On the Day of Judgement, "Fasting will say: O My Lord I prevented him from food and desires so accept my intercession for him." [Ahmad, al-Haakim and Abu Nu'aim, Hasan]
There are in the month of Ramadhan in every day and night those to whom Allah grants freedom from the Fire, and there is for every Muslim an supplication which he can make and will be granted." [al-Bazzaar, Ahmad, Saheeh]
The Prophet said: He who gives food for a fasting person to break his fast, he will receive the same reward as him, except that nothing will be reduced from the fasting persons reward." [Ahmad, at-Tirmidhee, Ibn Maajah, Ibn Hibbaan, Saheeh].
"When My servants ask thee concerning Me, I am indeed close (to them):I listen to the prayer of every suppliant when he calleth on Me: let them also, with a will, listen to My call, and believe in Me: that they may walk in the right way." (Q 2:186)
