❖ The Question:
Is it true that during the time of ʿUmar ibn al-Khaṭṭāb رضي الله عنه, the Nile River in Egypt stopped flowing, and upon receiving a letter from him addressed to the Nile, it began flowing again?❖ The Reported Incident:
This story is commonly narrated as follows:When Egypt was conquered, locals informed ʿAmr ibn al-ʿĀṣ رضي الله عنه that the Nile would not flow unless a young girl was sacrificed and thrown into the river on the 11th night of a particular month.
Rejecting this pagan custom, ʿAmr wrote to the Caliph, ʿUmar ibn al-Khaṭṭāb رضي الله عنه, who sent back a letter addressed to the Nile, saying:
"From the servant of Allah, ʿUmar, to the Nile of Egypt: If you flow on your own, then do not flow. But if you flow by the command of Allah, the One, the Irresistible, then I ask Allah to make you flow."
This letter was then thrown into the Nile, and reportedly, the river immediately began flowing and rose by ten cubits.
❖ Sources Where This Incident is Mentioned:
This story is found in the following works:- Futūḥ Miṣr by Ibn ʿAbd al-Ḥakam (pp. 150–151)
- Kitāb al-ʿAẓamah by Abū al-Shaykh (4/1424, Ḥadīth 937)
- Sharḥ Iʿtiqād Ahl al-Sunnah by al-Lālikāʾī (1/240, Ḥadīth 72 – section on Karamāt)
- Karamāt al-Awliyāʾ (p. 26)
- Tafsīr Ibn Kathīr (3/464 under Sūrah al-Sajdah: 27)
- Musnad al-Fārūq (1/223–224)
- al-Bidāyah wa al-Nihāyah (1/23)
❖ Authenticity Analysis:
The chain of narration includes:- ʿAbdullāh ibn Laḥīʿah – a mudallis narrator (i.e., one who omits weak narrators)
- [Refer to: Ṭabaqāt al-Mudallīsīn 5/140]
- The narration is muʿanʿan (ambiguous in narration style), and
- Qays ibn al-Ḥajjāj is a Tābiʿ al-Tābiʿī (successor of the successors), whose teacher is unknown, making this an anonymous (majhūl) narration.

❖ Scholarly Verdict:
This narration is considered fabricated or unfounded due to the weakness in its chain, specifically because:- Ibn Laḥīʿah is a mudallis and has been widely criticized for unreliability.
- There is no known narrator between Qays ibn al-Ḥajjāj and the source of the story.
- Thus, it falls under narrations from the unknown (ظلمات).

❖ Final Verdict:

It should not be used to establish belief, derive rulings, or to promote stories of miracles related to the Caliph ʿUmar رضي الله عنه or the river Nile.
