Before the Hour there will be tribulations like pieces of smoke

It is narrated from al-Hasan al-Basri that al-Dahhak bin Qays wrote to Qays bin al-Haytham at the time of the death of Yazid bin Mu'awiyah: Peace be upon you. To proceed: I heard the Messenger of Allah (peace and blessings be upon him) say: "Before the Hour there will be trials like pieces of smoke, in which a man's heart will die just as his body dies. In that time a man will be a believer in the morning and a disbeliever in the evening, and a believer in the evening and a disbeliever in the morning. People will sell their religion for a small gain of this world." And now Yazid has died, while you are our brothers and our own kin.

Abu al-Ala bin Abdullah bin al-Shikhkhir states: I heard al-Dahhak bin Qays al-Fihri say: I heard the Messenger of Allah (peace and blessings be upon him) say: "When a man comes to a people and they say to him 'Welcome', then he will be welcomed on the day he meets his Lord. And when a man comes to a people and they say to him 'May you have drought and hardship', then there will be drought and hardship for him on the Day of Resurrection."

Sayyiduna al-Dahhak bin Qays (may Allah be pleased with him) states that there was a woman in Madinah named Umm Atiyyah who used to circumcise women. The Messenger of Allah (peace and blessings be upon him) said to her: "Cut slightly and do not cut deeply, for that is better for the radiance of the face and more pleasing to the husband."
