وَيَٰقَوْمِ لَا يَجْرِمَنَّكُمْ شِقَاقِىٓ أَن يُصِيبَكُم مِّثْلُ مَآ أَصَابَ قَوْمَ نُوحٍ أَوْ قَوْمَ هُودٍ أَوْ قَوْمَ صَٰلِحٍۢ ۚ وَمَا قَوْمُ لُوطٍۢ مِّنكُم بِبَعِيدٍۢ
And, O my people! Let not the schism with me cause you to sin so that there befall you that which befell the folk of Noah and the folk of Hud, and the folk of Salih; and the folk of Lot are not far off from you.
Surah Hud(11:89)

Fasting
Chapter: Observing Saum on the first day of 'Eid-ul-Adha.
Narrated Abu Huraira:
Two fasts and two kinds of sale are forbidden: fasting on the day of `Id ul Fitr and `Id-ul-Adha and the kinds of sale called Mulamasa and Munabadha. (These two kinds of sale used to be practiced in the days of Pre-Islamic period of ignorance; Mulamasa means when you touch something displayed for sale you have to buy it; Munabadha means when the seller throws something to you, you have to buy it.)
