Surah An-Naazi'aat(79:11)
Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: What tricks and means of security may be adopted
Narrated 'Abdullah bin Umar (ra):
Once, Allah's Messenger (ﷺ) accompanied by Ubai bin Ka'b set out to Ibn Saiyyad. He was informed that Ibn Saiyyad was in a garden of date palms. When Allah's Messenger (ﷺ) entered the garden of date-palms, he started hiding himself behind the trunks of the palms while Ibn Saiyyad was covered with a velvet sheet with murmurs emanating from under it. Ibn Saiyyah's mother saw Allah's Messenger (ﷺ) and said, "O Saf! This is Muhammad." So Ibn Saiyyad got up. Allah's Messenger (ﷺ) said, "If she had left him (in his state), the truth would have been clear."
