It was narrated that Abdullah bin Zubair said: "Uthman bin "Affan addressed the people and said: O people! I heard a Hadith from the Messenger of Allah ﷺ and nothing kept me from narrating it to you except for the fact that I did not want to lose you and your companionship. So it is up to you. I heard the Messenger of Allah ﷺ saying: "Whoever spends a night guarding the frontier in the cause of Allah, it will be lIke a thousand nights spent in fasting and prayer." (Daif)
