168. Subhaanal-lathee yusabbihur-ra'du bihamdihi walmalaa'ikatu
min kheefatihi.
Glory
is to Him Whom thunder and angels glorify due to fear of Him.
Reference: Whenever
Abdullah bin Zubair (RA) would hear thunder, he would abandon all
conversation and say this supplication. See Al-Muwatta' 2/992. It was
graded authentic by Al-Albani as a statement of Abdullah bin Zubayr
only.
“Prayer (Salat) is the most important practice in Islam. Allah has ordered the Muslims to be mindful of it. The Holy Qur'an says:"Guard strictly your prayers, especially the Middle Prayer, and stand before Allah with all devotion.”
