Bismillah

Thank you for your question. In the same way that a limitless God cannot be captured in images, He cannot be captured or fully described in words. Rather, words, such as His most beautiful Names are limitless as they are connected to His unlimited Essence.

Bismillah

Thank you for your question. When ijma and the aql are included in the sources of Islamic law in the school of Ahl al-Bayt (as) it is with specific terminological meanings that are not the same as other schools of thought. 

Ijma is a source of law if the view of the Imam (as) is included within the view of the community. Not when the community is agreed without the opinion of the Imam (as) being included.

Yes it is allowed for every Muslim to invest his money after being sure that money will not be invested in unlawful business i.e. alcohol, interest, etc.

Khums will be applicable on the investment on the date of Khums.

Wassalam.

It is recommended for the wife to sleep with her husband touching his body, and for the husband to be kind and gentle with his wife always specially when they are sleeping together . The side which is usually recommended for every one to sleep on is the right side of the body but for husband and wife sleeping together, they should sleep is the way which suits both of them. Husband should not give his back to his wife, nor wife should give her back to her husband.

Wassalam.

You must do every thing you can to return the money to its owners either directly to them or to their inheritors if they are dead.

If you tried your best and could not reach to them, then it must be given to the Marja' of Taqleed who will distribute it to the poor as Majhool al-Maalik (unknown owner) on behalf of the real owners.

Wassalam.
