866. hadíth
وَ رَوَى زُرَارَةُ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «تُؤَذِّنُ وَ أَنْتَ عَلَى غَيْرِ وُضُوءٍ فِي ثَوْبٍ وَاحِدٍ قَائِماً أَوْ قَاعِداً وَ أَيْنَمَا تَوَجَّهْتَ وَ لَكِنْ إِذَا أَقَمْتَ فَعَلَى وُضُوءٍ مُتَهَيِّئاً لِلصَّلاَةِ.
Zurarah narrated from Imam Muhammad ibn Ali Al-Baqir (a.s) that He said: "You may give the adhan (call to prayer) without being in a state of wudu (ritual purity), wearing a single garment, whether standing or sitting, and in any direction you face. However, when you perform the iqamah (second call to prayer), you must be in a state of wudu, prepared for the prayer."
