عَنْ أَبِي هُرَيْرَةَ رضي الله عنه أَنَّ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَجْعَلْ فِي أَنْفِهِ ثُمَّ لِيَنْثُرْ، وَمَنِ اسْتَجْمَرَ فَلْيُوتِرْ، وَإِذَا اسْتَيْقَظَ أَحَدُكُمْ مِنْ نَوْمِهِ فَلْيَغْسِلْ يَدَهُ قَبْلَ أَنْ يُدْخِلَهَا فِي وَضُوئِهِ، فَإِنَّ أَحَدَكُمْ لاَ يَدْرِي أَيْنَ بَاتَتْ يَدُهُ». ولفظ مسلم: «إِذَا اسْتَيْقَظَ أَحَدُكُمْ مِنْ نَوْمِهِ فَلَا يَغْمِسْ يَدَهُ فِي الْإِنَاءِ حَتَّى يَغْسِلَهَا ثَلَاثًا، فَإِنَّهُ لَا يَدْرِي أَيْنَ بَاتَتْ يَدُهُ».
Imepokewa Kutoka kwa Abuu Huraira -Radhi za Allah ziwe juu yake- yakwamba Mtume -Rehema na amani ziwe juu yake- amesema: "Atakapotawadha mmoja wenu basi na aweke maji puani mwake kisha ayapenge, na atakayestanji kwa mawe basi afanye yawe witiri, na atakapo amka mmoja wenu toka usingizini basi na aoshe mikono yake kabla ya kuingiza ndani ya chombo chake, kwani mmoja wenu hajui ni wapi ulilala mkono wake". Na lafudhi ya Muslim: "Atakapoamka mmoja wenu kutoka usingizini kwake basi asizamishe mkono wake ndani ya chombo mpaka auoshe mara tatu, kwani hajui ni wapi ulilala mkono wake".
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "When any of you performs ablution, let him sniff water in his nose and then blow it out. Whoever cleans his private parts with stones, let him do so with an odd number of stones. Whoever wakes up from his sleep, let him wash his hand before putting it in the water container of ablution, for none of you knows where his hand was during his sleep." The wording of Muslim reads: "Whoever wakes up from his sleep, let him not put his hand in the water container until he washes it three times, for he does not know where his hand was during his sleep."
Ni wajibu kupandisha maji puani wakati wa udhu, nako ni: Kuingiza maji puani kwa njia ya pumzi, na pia ni wajibu kuyapenga, nako ni: Kuyatoa maji puani kwa njia ya pumzi.
Inapendeza kupenga kwa witiri.
Ni sheria kuosha mikono miwili baada ya kutoka usingizini mara tatu.
