Is it desirable to give sadaqah (voluntary charity) on Laylatul Qadr?
Yes, very much so, for three related reasons:
Throughout the entire month of Ramadan, Allah greatly multiplies the divine reward of all good deeds done with the intention to please and worship Him alone.
Moreover, the Prophet, on him be peace, specifically singled out the voluntary ṣadaqah charity given in Ramadan as the very best charity.
Ibn ‘Abbas, a youthful cousin of the Prophet, on him be peace, renowned for his knowledge of the Quran and the wisdom of its Messenger, reports that the Companion Anas asked the Prophet, on him be peace:
“ ‘What is the best charity?’ He said: ‘A charity in Ramadan.’ ”
Yet of all Ramadan’s days of divine rewards, none approaches Laylatul Qadr, the Night of Empowering Decree, on which every good deed and act of worship Allah rewards as more than a thousand months. That’s as if one has done that particular act continuously for 83 years and 4 months. This is a lifetime of divine recompense obtained in just a few hours of striving.
This means $1 of ṣadaqah given on Laylatul Qadr will grow to at least $30,000 with Allah’s special nurture of it.
Allah Himself rewards the worship of fasting according to a divine magnitude over and above all other worship of Him.
Ramadan’s fast gives those who do it – “unseen” by all but Allah – a power in how it pleases Allah and in the sense of how Allah raises its divine reward. The Prophet, on him be peace, said:
Indeed, your Lord says: ‘Every good deed of the Child of Adam shall be the like of 10 to 700 extra, but the fast is for Me, and I shall reward for it (Muslim, no. 115).
This indicates fasting’s reward weighs heavier than all other good deeds of worship in one’s divine scales on the Day of Judgment. This, too, Allah augments exponentially by virtue of Laylatul Qadr.
The Prophet’s Way, or Sunnah, is distinguished by his unparalleled generosity at all times. Yet he increased his already unequaled charitable giving greatly in Ramadan. This establishes that the Muslim’s generosity through ṣadaqah should vastly increase in Ramadan.
Ibn ‘Abbas said:
Ever was the Prophet, on him be peace, the most generous of people. Yet he was even more generous in Ramadan, for then he would meet [the Archangel] Gabriel. Indeed, Gabriel, on him be peace, would meet him in every night of Ramadan, and the Prophet would review with him the Quran. Then would the Messenger of God, on him be peace, become more generous in deeds of charity than the gusting of a heaven-sent wind (Bukhari, no. 3554).
Note also that since the close of Heavenly Revelation with the completion of the Quran, Laylatul Qadr is the only night of the year that the Archangel Gabriel, by the command of his Lord, again descends to earth.
