The Prophet (SAWA) said, ‘I advise both the present and the absent ones from my community to accept the invitation of a fellow Muslim, even if it be five miles away, for verily that is a part of religion.
رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): أُوصِي الشاهِدَ مِن اُمَّتي والغائبَ أن يُجِيبَ دَعوَةَ المُسلِمِ ـ ولَو على خَمسَةِ أميالٍ ـ ؛ فإنّ ذلكَ مِن الدِّينِ.
