The discussion about mercy in the month of Ramadan begins with the privilege of fasting on Muslims throughout this month, based on a hadith qudsi narrated from Abu Hurairah RA that the Prophet SAW said: That Allah SWT has said:
"Every good deed of the son of Adam is for himself except fasting, indeed fasting is for Me and I myself will give the reward".
(Narrated by Al-Bukhari and Muslim)
Likewise with a piece of hadith narrated from Abu Hurairah RA that the Prophet SAW said: That Allah SWT has said:
"Every act of the son of Adam will be multiplied 10 times like it up to 700 times, except for fasting because fasting is for Me and I am the one who rewards it".
(Narrated by Al-Bukhari and Muslim)
From the two pieces of hadith above we can understand that fasting is an obligatory act of worship that has a very high position in the eyes of Allah SWT.
According to some scholars, the double gifted by Allah SWT for those who fast can reach up to an unlimited amount or infinity.
Next, the mercy revealed by Allah SWT in the month of Ramadan can be described by the forgiveness that Allah SWT offers to believers as in the hadith narrated from Abu Hurairah:
Once when the Prophet SAW ascended the pulpit, His Majesty SAW said: Amen, Amen, Amen. His Majesty SAW was asked: "O Messenger of Allah, when you ascended the pulpit, you said amen, amen, amen ". Then the Messenger of Allah, peace and blessings be upon him, said: "Indeed Jibril AS has come to me, and Jibril said: Whoever meets the month of Ramadan but is not forgiven for it, he will be put in hell and kept away (from mercy) by Allah SWT. Say Amen (O Muhammad). So I said: Amen "
(Narrated by Ibn Hibban)
The above hadith mentions the loss of people who were in the month of Ramadan but did not take advantage of that opportunity to obtain forgiveness from Allah SWT.
Mercy in this glorious month of Ramadan is also closely related to the revelation of the Qur'an as described by Allah SWT in surah al-Baqarah verse 185 which means:
"(The time you are required to fast is) the month of Ramadan in which the Al-Quran was revealed, as guidance for all mankind, and as evidence that explains the guidance and (explains) the difference between right and wrong".
Imam Fakhruddin al-Razi in his interpretation Mafatih al-Ghaib stated that the glory of Ramadan is due to two great Islamic teachings happening at the same time, namely the obligation of fasting and the revelation of the Qur'an.
Therefore, the grace and blessings of these two great acts of worship cause Ramadan to become a blessing for Muslims.
