وَيُكْرَهُ أَنْ يُقِيمَ عَلَى غَيْرِ وُضُوءٍ، أَوْ يُؤَذِّنَ وَهُوَ جُنُبٌ
Translation: It is disliked to pronounce the iqamah without wudu, or to give the adhan while in a state of janabah.
Two distinct disliked situations appear:
1. Pronouncing iqamah while in minor ritual impurity, when prayer is about to commence.
2. Pronouncing adhan while in janabah, a state of major ritual impurity that has a stronger ruling than ordinary lack of wudu.
