The Messenger of Allah ﷺ said, "The distance between the two doors of Paradise is a journey of forty years, yet a day will surely come when people will press against it like thirsty camels crowding at a watering place after five days without water."
قال رسول الله ﷺ: إن ما بين مصراعي الجنة مقدار أربعين عاما، وليأتين عليه يوم يزاحم عليه كازدحام الإبل وردت لخمس ظماء.

Tabarani narrated it in Kabir (14/338, no. 14970), reporting from Ibrahim bin Matawayh al-Isbahani, who said, "Muhammad bin Sadran narrated to us," who said, "Yaqub bin Ishaq Hadrami narrated to us," who said, "Zurayk bin Abu Zurayk narrated to us," from Muawiya bin Qurra, from Abdullah bin Salam, and he related it. Its isnad is hasan because of Ibrahim bin Matawayh, Muhammad bin Sadran, and Yaqub bin Ishaq Hadrami, since all of these are narrators whose hadith is graded hasan.Haythami said in Majma (10/397), "Tabarani narrated it, and it contains Ruzayk bin Abu Ruzayk, whom I do not know, but the rest of its narrators are trustworthy."I say, he did not recognize him because the name had become corrupted in his copy as "Ruzayk bin Abu Ruzayk," with the ra placed before the za, whereas the correct form is "Zurayk bin Abu Zurayk," with the za placed before the ra. He is Abu Nadr, and it is also said Abu Nadra al-Basri. Bukhari gave his biography in Tarikh al-Kabir, as did Ibn Hibban in Thiqat, and Ibn Abu Hatim in Jarh wa Tadil (3/624), where he reported from Ibn Main that he considered him trustworthy, and likewise Ibn Junayd also considered him trustworthy.
