Check these picture out below, SubhanAllah, devoted Muslims of all ages, who seek to pray at the prescribed times regardless of where they are.
Rasulullah [SallAllahu Alayhi WaSallam] said,
"Pray while standing and if you can't, pray while sitting and if you cannot do even that, then pray lying on your side."(Sahih Bukhari Volume 2 Book 20 No.218)
وإن كنت من ( المتكاسلين )
فستموت ميتة ( الخاسرين )
فلاتدع الصلاة تفوتك
Do not miss a prayer
Do not die a loser’s death
والله تعالى يقول : (( إِنَّ الصَّلاَةَ كَانَتْ عَلَى الْمُؤْمِنِينَ كِتَابًا مَّوْقُوتًا )) .
Allah swt says in the Quran that prayer is prescribed upon the believers according to a precise timely record
صَـلُّوا قــَـبْلَ أنْ يُصَلَّى عـَلـَـيْكُمْ
Pray before you are prayed upon
This is an amazing picture of a diver, praying underwater - I am not sure what the Fiqh issue is around this is.
Therefore, we should not add excuses to missing our obligation of Salaah - we must pray all 5 prayers daily Insha'Allah!
