عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا تَسْتَقْبِلُوا وَلَا تُحَفِّلُوا وَلَا يَنْعِقْ بَعْضُكُمْ لِبَعْضٍ
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: Do not face the Qiblah at the time of relieving yourselves, do not withhold (animals') milk to deceive, and do not call out to each other like the shepherds of goats.
