The purpose of Fasting is that you’re able to master your desires. Ramadan is a good time to get rid of habits which are non-productive or a waste of time. It teaches you how to control yourself better.
This month is the training period for the believers.
The purpose is not to overindulge yourself in eating and drinking and then lie down like an abandoned animal. You’re not an animal, respect your body and respect the sanctity of this month by focusing on eating just enough to sustain you through your day.
Don’t remain behind in catching up on the goods deeds this month. The best part in Ramadan is standing the night in prayer with the Book of Allah, Quran. Recite it to the best of your ability and if you’re at a masjid, then follow along attentively. You’ll be rewarded for paying attention to the recitation of the Quran.
In Surah al-Ahqaf, Allah mentions the tribe of Jinn that listened to the recitation of the Quran attentively and immediately became believers and passed on the message others.
وَإِذْ صَرَفْنَا إِلَيْكَ نَفَرًا مِّنَ الْجِنِّ يَسْتَمِعُونَ الْقُرْآنَ فَلَمَّا حَضَرُوهُ قَالُوا أَنصِتُوا فَلَمَّا قُضِيَ وَلَّوْا إِلَى قَوْمِهِم مُّنذِرِينَ
قَالُوا يَا قَوْمَنَا إِنَّا سَمِعْنَا كِتَابًا أُنزِلَ مِن بَعْدِ مُوسَى مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ يَهْدِي إِلَى الْحَقِّ وَإِلَى طَرِيقٍ مُّسْتَقِيمٍ
يَا قَوْمَنَا أَجِيبُوا دَاعِيَ اللَّهِ وَآمِنُوا بِهِ يَغْفِرْ لَكُم مِّن ذُنُوبِكُمْ وَيُجِرْكُم مِّنْ عَذَابٍ أَلِيمٍ
29. And (remember) when We sent towards you (Muhammad ) Nafran (three to ten persons) of the jinns, (quietly) listening to the Qur’an, when they stood in the presence thereof, they said: “Listen in silence!” And when it was finished, they returned to their people, as warners.
30. They said: “O our people! Verily! We have heard a Book (this Qur’an) sent down after Musa (Moses), confirming what came before it, it guides to the truth and to a Straight Path (i.e. Islam).
31. O our people! Respond (with obedience) to Allah’s Caller (i.e. Allah’s Messenger Muhammad ), and believe in him (i.e. believe in that which Muhammad has brought from Allah and follow him). He (Allah) will forgive you of your sins, and will save you from a painful torment (i.e. Hell-fire).
They were quicker to profess faith than the people of Quraish around Rasullah ﷺ. Imagine their reward for responding to the call of the Messenger swiftly.
You still have time to catch up, ask Allah to give you the strength to maximise your reward during this blessed month of mercy.
