Epistle to the Son of the Wolf — Paragraph 264
Source (Persian)
و عن رسول اللّه - صلّی اللّه عليه و سلّم - انّه قال طوبی لمن زار عکّاء و طوبی لمن زار زائر عکّاء * طوبی لمن شرب من عين البقر و اغتسل من مائها فانّ الحور العين يشربن الکافور الّذي فی الجنّة من عين البقر و عين سلوان و بئر زمزم * طوبی لمن شرب من هؤلاء العيون و اغتسل من مائهنّ فقد حرّم اللّه عليه و علی جسده نار جهنّم يوم القيامة *
Translation
The Apostle of God - may the blessings of God and His salutations be upon Him - is reported to have said: "Blessed the man that hath visited ‘Akká, and blessed he that hath visited the visitor of ‘Akká. Blessed the one that hath drunk from the Spring of the Cow and washed in its waters, for the black-eyed damsels quaff the camphor in Paradise, which hath come from the Spring of the Cow, and from the Spring of Salvan (Siloam), and the Well of Zamzam. Well is it with him that hath drunk from these springs, and washed in their waters, for God hath forbidden the fire of hell to touch him and his body on the Day of Resurrection."
