Taqdeer

Q: Allah Ta'ala says in the holy quran "In order that you may not grieve at the things that you fail to get, nor rejoice over that which has been given to you. And Allah like not prideful boasters" Sura hadeed ayah 23

My question is that sometimes we lose or fail to get something because of our wrong choices or decisions (we make these wrong choices by mistake, carelessness, not judging the matter judiciously or out of arrogance or ignorance). We turn out to be loser (ok this was written in our destiny) but should we not grieve if we made a wrong choice? Are we not responsible for what is written in our destiny? Allah is just so how can he make one's destiny good and other's bad. It is also said that everything happens for good. Is it applicable in the case we made a wrong choice? So should we not grieve for our bad choices in life?

Associating with shias

Q: At our University we have Salaat al-Jumu'a in which 85% of the followers are of the Ahlus Sunnah wa al-Jama'a and 15% are of the Twelver Shi'a. The Shi'a stand in our Saf (rows) and pray with us. They do not bother us, nor do we bother them. But at the end of the day they are Shi'a, so should we the 85% tell them to leave and not pray with us? 

We have overheard their discussions in which many say wrong ahadith/rewayat, but their leader on our campus I have heard many a times scold the Shi'a and say that Hazrat Aisha is our Mother and is to be respected even if she made a mistake. Their leader keeps them in check. So are they Muslim? Can they pray with us?

Necklace that has a design of a cross

Q: There is a brother who is now reverted toIslam for 5 months. Few years ago when his mother died, he got from his mother a necklace with a Christian cross as heritage. And he promised his mother to that he also will give it away to his children as heritage. Now as he has reverted to Islam, what he has to do with the necklace? Currently he is keeping it in his house in a box. Can he keep this and give it later to his children. The necklace is a heritage piece which is over 200 years in the family.
