The Messenger of Allah ﷺ said, "Whoever intends to perform Hajj should hasten to do so, for one may fall ill, an animal may stray, or a need may arise."
حدثنا علي بن محمد وعمرو بن عبد الله قالا حدثنا وكيع حدثنا إسمعيل أبو إسرائيل عن فضيل بن عمرو عن سعيد بن جبير
قال رسول الله ﷺ من أراد الحج فليتعجل فإنه قد يمرض المريض وتضل الضالة وتعرض الحاجة
Takhrij, [hasan]. Ahmad narrated it, 1/214, 355, from Waki with the same wording.Abu Israil Mulai is daif, as stated in Kashif by Dhahabi, 1/72, and elsewhere. It has other routes narrated by Abu Dawud, no. 1732, and by Ahmad, 1/225, and others. Ahmad's chain is hasan, and Hakim graded it sahih, 1/448. I say, Abu Safwan's hadith is hasan according to the more correct view.
