It is in our nature to decline some invitations they receive. This article will look into that one special invitation most people neglect to accept. This invitation has a greater power that could give people anything and everything they want in life if they take the chance, while it could also lead people to great distress for failing to acquire it.

Because this invitation is from the Lord of the Universe, Allah Subhanahu Wa Ta'ala, He questions His slaves what they desire. He invites His salves to call upon for His mercy. He doesn't limit this invitation. He summons them to ask for anything and everything. Not only that, but He also affirms to fulfil the needs of those who call out for him. The following Hadith of Messenger (ﷺ) confirms this to be true.

As stated in Sahih al-Bukhari, Book 19: Prayer at Night (Tahajjud), Chapter 14: Offering Salat (prayer) and invoking Allah in the last hours of the night, Hadith 1145

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، وَأَبِي عَبْدِ اللَّهِ الأَغَرِّ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ يَنْزِلُ رَبُّنَا تَبَارَكَ وَتَعَالَى كُلَّ لَيْلَةٍ إِلَى السَّمَاءِ الدُّنْيَا حِينَ يَبْقَى ثُلُثُ اللَّيْلِ الآخِرُ يَقُولُ مَنْ يَدْعُونِي فَأَسْتَجِيبَ لَهُ مَنْ يَسْأَلُنِي فَأُعْطِيَهُ مَنْ يَسْتَغْفِرُنِي فَأَغْفِرَ لَهُ ‏"‏‏.‏

Meaning: Narrated Abu Huraira: Allah's Messenger (ﷺ) (p.b.u.h) said, "Our Lord, the Blessed, the Superior, comes every night down on the nearest Heaven to us when the last third of the night remains, saying: "Is there anyone to invoke Me, so that I may respond to invocation? Is there anyone to ask Me; so that I may grant him his request? Is there anyone seeking My forgiveness; so that I may forgive him?" 

• Sahih al-Bukhari 1145-

The main reason to bring up this Hadith is to remind those who accepted this invitation of Allah Subhanahu Wa Ta'ala and performed Tahajjud in Ramadan and forgets about it afterwards. You will be amongst the failures if you neglect to perform Tahajjud as you performed it in Ramadan. Hence, even though you do not do voluntary fasting, do not abstain yourselves from performing Tahajjud
