Narrated 'Ubada bin As-Samit:"Allah's Messenger (ﷺ) went out to inform the people about the (date of the) night of decree (Al-Qadr) but there happened a quarrel between two Muslim men. The Prophet (ﷺ) said, "I came out to inform you about (the date of) the night of Al-Qadr, but as so and so and so and so quarrelled, its knowledge was taken away (I forgot it) and maybe it was better for you. Now look for it in the 7th, the 9th and the 5th (of the last 10 nights of the month of Ramadan)
Ubada bin Samit (رضی اللہ عنہ) bataate hain ke Allah ke Rasool (ﷺ) Shab-e-Qadr ki tareekh bataane nikle, lekin do Musalmanon mein jhagda ho gaya. Nabi (ﷺ) ne farmaya: "Main tumhe Shab-e-Qadr ki tareekh bataane aaya tha, magar falaan-falaan ke jhagde ki wajah se woh ilm utha liya gaya (main bhool gaya), shayad yeh tumhare liye behtar ho. Ab ise (Ramadan ke aakhri das dinon ki) 7, 9 aur 5 taareekh mein talaash karo."
