أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مِسْعَرٍ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا أُمْطِرَ قَالَ ‏"‏ اللَّهُمَّ اجْعَلْهُ صَيِّبًا نَافِعًا ‏"‏ ‏.‏
Translation
It was narrated from 'Aishah that

When it rained the Messenger of Allah would say: "Allahummaj'alhu Sayyiban nafi`a. (O Allah, make it beneficial rain)."

Comment

The Book of Praying for Rain (Al-Istisqa') - Sunan an-Nasa'i

Hadith Reference: Sunan an-Nasa'i 1523

Textual Analysis

The supplication "Allahummaj'alhu Sayyiban nafi`a" consists of two essential components: "Sayyiban" meaning abundant, copious rain that penetrates deeply into the earth, and "nafi`a" meaning beneficial and useful.

This comprehensive dua encompasses both quantitative and qualitative aspects of rainfall - seeking both abundance and benefit.

Juridical Ruling

This practice is established as a confirmed Sunnah (Sunnah mu'akkadah) that Muslims are recommended to recite when rain descends.

The timing for this supplication is specifically when the rain is actually falling, not before or after.

Spiritual Dimensions

This teaching instills constant remembrance of Allah during both times of ease and difficulty, recognizing rain as a divine mercy rather than mere natural phenomenon.

The Prophet's instruction demonstrates the comprehensive nature of Islamic guidance, covering even moments we might consider mundane.

Practical Wisdom

By specifying "beneficial rain," the supplication seeks protection from potential harm that excessive rain might cause, such as floods or destruction.

This embodies the balanced approach of Islam - seeking blessings while simultaneously seeking protection from potential negative consequences.
