Islam gives human life the highest degree of importance and considers it is sacred. That is why we find many Quranic verses and Hadeeths encouraging marriage and having children. 

The term of " overpopulation" is not accepted by us at all. Who has the right to put limits to population then to claim that it is over?

If sources are utilized properly, there will be no question of overpopulation. Islam encourage utilizing the sources in better ways which will improve he quality of billions of human beings.

It is mentioned in Sunni books like Bukhari Vol 11 : (Donkey sees Shaitan) but I did not find it in our authentic books.

Nevertheless, what difference does it make for us in our worldly and religious life whether it is true or not? 

The world of Jinns is completely different world frm ours and we ae not allowed to seek any help from them as we read in Quran (And some men from humans were seeking refuge of the Jinn and the Jinns added on their hardships)(Al-Jinn ; 6).

Obligatory Hajj is Must on every Muslim who can perform it and no other worship can replace it. Visitation to Karbala is very great but not in stead of obligatory Hajj.

Visitation of Imam Husain (AS) in Karbala is greater in reward than recommended Hajj and Umra.

In Sunni books as well as Shia books, it is narrated that The Prophet Muhammad (SAWA) has clearly said:  My successors will be twelve , all of them from Bani Hashim.

This is one of Sunni very important books which narrated this Hadeeth:

Yanabee' Al-Mawaddah by Al-Qundoozi Al-Hanafi, Vol 3, Page 445.

The narration of Quraysh is the ne which has been publicized by those who dont want to mention Ahlul Bayt (AS).

They were people who thought that they can get the fruits of their garden with out giving its dues to the poor and decided to pluck the fruits next morning with out saying : If Allah wills. 

Allah sent fire which burn the garden while they were asleep. They lost every things as a result of their bad deeds.

This Verse was mentioned to inform about the disastrous result of the enemies of Allah in the Day of Judgment (يوم الفصل ), then it was mentioned after reminding them about what happened to those who committed the same bad before them, and how Allah destroyed them , warning the infidels that they will face the same here and hereafter. Then Allah reminds them about how He created them in this life which will end, where the infidels will face the disastrous results of their crimes.

Quranic verses confirm the virgin birth of Jesus. Sura Maryam; Verses 16 to 35.

It is worth mentioning that Prophet Jesus (Easa)(AS) is mentioned in Quran 25 times exactly like the number of the mention of Prophet Adam (AS) who is also mentioned in Quran 25 times. Allah (The Most Glorious) says in Quran ( Verily, the likeness of Jesus with Allah is the likeness of Adam, Allah created him from clay then told him be, and he was). Adam was created with out parents and Easa was created with out father. Both  are miraculous. 

Backbiting is a major sit which mentioned in Quran as eating the flesh of your dead brother. (And do not backbite each other, does any one from you like eating the flesh of his  dead brother, then you will hate him).

Backbiting is (Mentioning any Momin with anything which he / she does not like to be mentioned). If it was a true, then it s backbiting, but it was untrue then iy will be allegation which more dangerous.

Repenting from backbiting is Must otherwise it will lead to hellfire.
