Hadith text
Narrated Abu Huraira:Once Allah's Messenger (ﷺ) prayed two rak`at (instead of four) and finished his prayer. Dhul-Yadain asked him whether the prayer had been reduced or whether he had forgotten. Allah's Messenger (ﷺ) asked the people whether Dhul-Yadain was telling the truth. The people replied in the affirmative. Then Allah's Apostle stood up, offered the remaining two rak`at and then finished his prayer with Taslim and then said, "Allahu Akbar." He followed it with two prostrations like ordinary prostrations or a bit longer
Abu Huraira (رضی اللہ عنہ) se riwayat hai ke ek baar Allah ke Rasool ne do rakat (chaar ke bajaye) padh kar namaz khatam kar di. Dhul-Yadain ne pucha kya namaz kam hui ya Nabi bhool gaye. Allah ke Rasool ne logon se pucha kya Dhul-Yadain sach keh rahe hain. Logon ne haan kaha. Phir Allah ke Rasool khade hue, baaki do rakat padhi, phir Taslim se namaz khatam ki, phir "Allahu Akbar" kaha aur usi jaisa ya kuch lamba do sajda kiya.
