Marriage and destiny

Q: I have a question that confuses me often. I have read in the Islamic books that women is created from the left rib of the men and therefore matches are made before a person comes to this world. This means that each man and woman on earth has a match. Then what about the man who never gets married or women who never gets married when they have their match in the world. And if a person does not get married, what about his/her destined match? Does his match also does not get married? And those who pass away as a bachelor, does his women never gets married, as a person only gets married to those with whom they are destined to be with.

A dua to be recited in the morning and evening

Q: “Whoever says in the morning and in the evening Hasbi Allaah laa illaha illa huwa ‘alayhi tawwakaltu wa huwa rabb al-‘arsh il-‘azeem (Sufficient for me is Allaah, there is no God besides Him; in Him have I put my trust and He is the Lord of the mighty Throne), seven times, Allah, may He be exalted, will suffice him for what concerns him,” and it does not contain the additional phrase mentioned (“of the affairs of this world and the Hereafter”).

1. My question is whether this should be recited before or after the Fajr and Maghrib prayer or does the time just have to set in?

2. What is considered morning and evening according to Hanafi fiqh?

Tying the hair into a bun

Q: "Hadhrat Abu Hurairah (Radiyallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: “There will be two groups (in my ummat) who will be punished in Jahannum. These two groups I have not yet seen (i.e. they will emerge after my demise). One group will carry whips with them resembling the tails of cattle, with which they will (oppressively) lash the people. The second group will be those women who will wear clothes yet they will still be naked (i.e. tight fitting or flimsy clothing), they will attract men to themselves, and they themselves will be inclined towards them, their heads will resemble the humps of the Bukhti camels (i.e. they will wear buns which will be high like camel humps). They will not enter Jannah nor smell its fragrance, despite its fragrance being able to be perceived from a great distance away."

It is not permissible to wear high buns? I make a high bun when I'm sleeping because of the hair getting into my face. My hair is tied in a ponytail the rest of the day. Should I stopping making high buns at night?
