Bahjat al-Asrar preserves a later manaqib report attributed to the mother of Shaykh Abd al-Qadir al-Jilani (rahmatullahi alayh), Umm al-Khayr Fatima, saying that while he was still an infant he did not nurse during the daylight hours of Ramadan. The same report says that on a day when the crescent was hidden and people were uncertain whether Ramadan had begun, his refusal to nurse during the day was taken locally as a sign. The day was then regarded as a day of Ramadan. The account is presented here as a transmitted Qadiri manaqib story, not as an independently established early historical report.
According to the account, this behavior became something the family associated with the fasting hours of Ramadan. The central scene of the story comes on a day when the new crescent was obscured and people were uncertain whether the month had begun. In that uncertainty, the infant was again observed during the day, and he did not nurse.
The report says that people around the family treated this as a sign that the day belonged to Ramadan. The story then adds that the day was later recognized as a day of the month. In the Qadiri devotional memory surrounding Shaykh Abd al-Qadir al-Jilani, the episode therefore came to be remembered as an extraordinary Ramadan sign connected with his earliest childhood.
The story is simple in its sequence. His mother is said to have noticed that he did not nurse in Ramadan daylight. Then came a day of uncertainty because the crescent was hidden. The same daytime abstention was observed again, and those around him understood it as an indication that Ramadan had begun. Nothing more is needed to make the transmitted scene clear.
The source should also be kept in view. Bahjat al-Asrar is a later work of manaqib, and this particular infancy account is preserved there as a devotional report attributed through later transmission to Umm al-Khayr Fatima. For that reason, the public story should not be retold as though it were an early contemporary record or an authenticated hadith.
Presented within those limits, the account remains a memorable part of the Qadiri manaqib tradition: an infant who, according to the transmitted report, did not nurse during Ramadan daylight, and whose behavior on a clouded-crescent day was taken locally as a sign that the sacred month had begun.
Conclusion
The transmitted story remembers Shaykh Abd al-Qadir al-Jilani (rahmatullahi alayh) as an infant who did not nurse during Ramadan daylight and whose abstention was locally treated as a sign on a day when the crescent was hidden.
