Sleeping

Sleeping on one's stomach involuntarily

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? 

Bunk beds

Q: I would like to arrange triple bunks bed for my boys. Is this allowed? As I have heard you are not allowed to sleep on top of each other or you shouldn't sleep above each other. Please can you clarify this.

Sleeping on the floor

Q: A Hindu worker had come into my room. He then asked why I sleep on the floor despite having a normal bed. I was unsure how to explain, so I just replied that 'I find it more comfortable'. Was this the right thing to say? I sleep on the floor so that I can face the Qiblah whilst sleeping.
