قَالُوا۟ سُبْحَٰنَكَ مَا كَانَ يَنۢبَغِى لَنَآ أَن نَّتَّخِذَ مِن دُونِكَ مِنْ أَوْلِيَآءَ وَلَٰكِن مَّتَّعْتَهُمْ وَءَابَآءَهُمْ حَتَّىٰ نَسُوا۟ ٱلذِّكْرَ وَكَانُوا۟ قَوْمًۢا بُورًۭا
They will say: Be Thou Glorified! it was not for us to choose any protecting friends beside thee; but Thou didst give them and their fathers ease till they forgot the warning and became lost folk.
Surah Al-Furqaan(25:18)
Sahih al-Bukhari
Ablutions (Wudu')
Chapter: To perform ablution even on having no Hadath
Narrated Suwaid bin Nu`man:
In the year of the conquest of Khaibar I went with Allah's Messenger (ﷺ) till we reached As-Sahba' where Allah's Messenger (ﷺ) led the `Asr prayer and asked for the food. Nothing but saweeq was brought and we ate it and drank (water). The Prophet (ﷺ) got up for the (Maghrib) Prayer, rinsed his mouth with water and then led the prayer without repeating the ablution.
