Is this narration reliable?
The Messenger of Allah (sallallahu ‘alayhi wa sallam) said:
“Three things whomsoever protects, are truly my friends and whoever destroys them is my enemy; Prayer, fasting and impurity.”
Answer
Imam Tabarani (rahimahullah) has recorded this Hadith on the authority of Sayyiduna Anas (radiyallahu ‘anhu).
Sayyiduna Anas (radiyallahu ‘anhu) reported that Nabi (sallallahu ‘alayhi wa sallam) said: “Whomsoever protects three things will be my close friend [i.e. Allah will take care of him and protect him] and whomsoever is negligent regarding them is my true enemy [i.e Allah will take him to task and punish him]; [They are] Salah, Fasting [in Ramadan] and impurities (janabah) [i.e. ensuring that one takes a compulsory bath after impurities].”
(Al Mu’jamul Awsat, Hadith: 8956. Refer: Faydul Qadir, Hadith: 3427)
‘Allamah Haythami (rahimahullah) has declared a narrator weak. The Hadith is suitable to quote as an incentive for these deeds, as is the case with Hadiths of this nature.
