Using emojis

Q: Is it khilaaf-e-sunnah to use emojis that have laughing faces while chatting on WhatsApp? As our Prophet (sallallahu alaihi wasallam) didn't laugh showing his mubarak teeth.

Reward for performing salaah by applying itr, wearing a turban or after performing miswaak

Q:

1. Is there any hadith that states that the reward for praying salah applying itr (fragrance) is 70 times more than offering salah without applying itr?

2. The same reward I have heard for offering salah wearing an عمامة (turban) for men, is it stated in any hadith?

3. Is the above mentioned reward given for a person praying salah after doing Miswaak as well?

Looking after the wealth of an autistic person

Q:

1. If an autistic baaligh child does not know the value of wealth, will her wealth be like the wealth of a non-baligh orphan? Meaning that her wealth would be given to her guardians to use only in the interests of the child.

2. I have an autistic relative. I have some of her wealth in my possession for safe-keeping as I fear that if I give it to her parents, they may misuse it. Meaning that they may use it for their other children also (not only in the interests of the autistic child). What should I do with that wealth?

3. If I have that wealth in my possession for safe-keeping, and someone (non-baligh) uses it without my knowledge, would I have to pay back any amount to the autistic child?

Making fardh ghusal after sehri

Q: As the month of Ramadhaan approaches, I would like to ask the following:

1. If a person goes to sleep and upon waking up for sehri, he notices he is in need for a compulsory ghusal due to a dream he had. Can that person eat sehri, START HIS FAST and thereafter have a ghusal before fajr?

2. Or should he have a ghusal before sehri? (What if there is a fear of missing sehri?)

3. If a person does have a ghusal AFTER sehri before fajr, ONCE HE STARTED HIS FAST, will his fast be accepted/valid?

Studying astronomy

Q: "Is astrological study forbidden for us." I mean can we study it just to gain some new knowledge, not meant to use it for fortune telling... Just for getting knowledge about the effect of heavenly bodies on our natural behaviour.
