[Machine] The Messenger of Allah ﷺ said, "It does not matter if a person uses stagnant water that does not flow for purification. He also said, "When one of you wakes up, do not put his hand in the ablution water until he washes it, for he does not know where his hand has spent the night." This hadith was narrated by Muslim in the authentic collection from Muhammad ibn Rafi' from Abdur-Razzaq who said, "Az-Zuhri said, 'Imam Shafi'i said in old times, if a person kneads impure dough with it meaning with najis (impure) water, and then a animal eats it and feeds it to other animals, Imam Ahmad said, 'We have narrated from Ata and Mujahid that one should feed it to a chicken.'"  

قَالَ رَسُولُ اللهِ ﷺ لَا يُبَالُ فِي الْمَاءِ الدَّائِمِ الَّذِي لَا يَجْرِي ثُمَّ يُغْتَسَلُ مَنْهُ قَالَ وَقَالَ رَسُولُ اللهِ ﷺ إِذَا اسْتَيْقَظَ أَحَدُكُمْ فَلَا يَضَعْ يَدَهُ فِي الْوَضُوءِ حَتَّى يَغْسِلَهَا فَإِنَّهُ لَا يَدْرِي أَيْنَ بَاتَتْ يَدُهُ رَوَاهُمَا مُسْلِمٌ فِي الصَّحِيحِ عَنْ مُحَمَّدِ بْنِ رَافِعٍ عَنْ عَبْدِ الرَّزَّاقِ قَالَ الزَّعْفَرَانِيُّ قَالَ الشَّافِعِيُّ فِي الْقَدِيمِ فَإِنْ عَجَنَ بِهِ يَعْنِي بِالْمَاءِ النَّجِسِ عَجِينًا لَمْ يَأْكُلْ وَأَطْعَمَهُ الدَّوَابَّ قَالَ الْإِمَامُ أَحْمَدُ وَقَدْ رُوِّينَا عَنْ عَطَاءٍ وَمُجَاهِدٍ أَنَّهُ يُطْعِمُهُ الدَّجَاجَ
