Another hadith states, Allah has forbidden for any human to enter paradise before me, except that I look to my right and see a woman hastening to the gate of paradise. This is narrated by al-Khara'iti in Makarim al-Akhlaq from Abu Huraira, also with a weak chain of transmission. Lastly, the hadith of Mu'adh says, No woman harms her husband in this world except that his wife from among the maidens of paradise says, Do not harm him."

3. "The hadith "The dawn is not like this"—and he clasped his hand—"but the dawn is like this," and he placed one index finger on the other and spread them, indicating that it is horizontal, was reported by Ibn Majah from the narration of Ibn Mas'ud with a sound chain of transmission in a shortened form, without the indication with the hand and index fingers. It was also reported by Ahmad from the narration of Taliq ibn Ali, stating, "The dawn that is long in the horizon is not the real dawn; it is the horizontal red," and its chain of transmission is good."
