Ihram

My father went for Hajj last year, but he was very sick and was not able to wear the ihraam garments. What does he have to do?

Is it permissible for the pilgrim in ihraam to wash his entire body in order to cool down?

If a person puts on ihraam for ‘Umrah or Hajj, then he cancels it, what does he have to do?

Can we use miswak or unperfumed tooth paste,cream,lotion, patrolium jelly during haj days.

I went for umra recently from riyadh , I put the ihram at home without making the niyat thinking that I will do it on the plane before crossing the meeqat . unfortunately I did not hear the announcement about the meeqat on the plane and was unable to do the niyat because the plane had already crossed the meeqat . I made the decision to go to Mecca , on arriving in Mecca , I took the ihram off and put regular clothes on and drove to qarin-manzil in taif . there I put the ihram again and did the niyat of umra and came back to Mecca and performed the umra . please tell me if I did it right or I have to pay the penalty and if do have to pay the penalty then what I have to do . please respond.

I intend to go for Hajj this year, if Allaah wills, and I want to travel from Riyadh to Jeddah by air. When exactly should I enter ihraam?.
