عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رضي الله عنه قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «إِذَا شَكَّ أَحَدُكُمْ فِي صَلَاتِهِ، فَلَمْ يَدْرِ كَمْ صَلَّى ثَلَاثًا أَمْ أَرْبَعًا، فَلْيَطْرَحِ الشَّكَّ، وَلْيَبْنِ عَلَى مَا اسْتَيْقَنَ، ثُمَّ يَسْجُدُ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ، فَإِنْ كَانَ صَلَّى خَمْسًا شَفَعْنَ لَهُ صَلَاتَهُ، وَإِنْ كَانَ صَلَّى إِتْمَامًا لِأَرْبَعٍ كَانَتَا تَرْغِيمًا لِلشَّيْطَانِ».
Imepokelewa kutoka kwa Abuu Saidi Al-Khuduriy -Radhi za Mwenyezi Mungu ziwe juu yake- amesema: Amesema Mtume -Rehema na amani ziwe juu yake-: "Atakapopata shaka mmoja wenu katika swala yake, akawa hajui kaswali rakaa ngapi tatu au nne? Basi aachane na shaka na ajenge yakini (uhakika), kisha atasujudu sijida mbili kabla hajatoa salamu, ikiwa atakuwa kaswali rakaa tano basi zitamtetea katika swala yake, na kama aliswali kukamilisha nne; basi hiyo itakuwa ni kumvunja moyo shetani."
Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "When anyone of you is in doubt about his prayer, not knowing how much he prayed, three or four, let him dispel the doubt and build upon what he is certain about, then perform two prostrations before making Taslīm. If he has prayed five, they will make his prayer even-numbered, and if he has prayed exactly four, they will be humiliation for the devil."
Mwenye kuswali akiitilia shaka swala yake na akawa hakupata ufumbuzi wa moja kati ya mambo mawili, basi aondoe shaka na afanyie kazi uhakika, ambao ni uchache, basi atatimiza swala yake na atasujudu kwa ajili ya kusahau kabla hajatoa salamu kisha atatoa salamu.
Sijida hizi mbili ni njia ya kurekebisha swala, na kumrudisha Shetani katika hali ya udhalili na unyonge, mbali na alichotaka.
Shaka iliyoko katika Hadithi ni kusitasita bila ya kupata majibu, hivyo ikipatikana dhana na akapata majibu basi atafanyia kazi dhana yake.
Himizo la kupambana na wasi wasi na kuuzuia kwa kutekeleza amri ya sheria.
