Q: Is it ok to put my daughter's bed in my own big master bedroom as there is no physical relation between me and my husband due to perpertual illness of him.

She has no siblings. It is only the 3 of us.

Q: It is said in the sunnah that it is better to fall asleep on the right side, and that it is disadvised to sleep on the stomach because in the Hadith, it is said:

عَنْ أَبِي هُرَيْرَةَ، قَالَ : رَأَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَجُلًا مُضْطَجِعًا عَلَى بَطْنِهِ فَقَالَ : إِنَّ هَذِهِ ضِجْعَةٌ لَا يُحِبُّهَا اللَّهُ

Similarly, we hear that it is not advisable to sleep on the left side. Now, if someone starts to lie on the right side. Then, involuntarily during his sleeping, he turns on the left side, or puts himself on the stomatch, will she have the totality of the rewards or not?
