Saying "As-Salatu Khayrun Minan-Nawm" Twice in Fajr Adhan Is Sunnah

Hadith on the Sunnah of Fajr Adhan​

Narrated by Anas bin Malik (رضي الله عنه):
"It is Sunnah that when the Mu'adhin reaches ‘Hayya ‘ala al-Falah’ in the Fajr Adhan, he should then say:
‘As-Salatu Khayrun Minan-Nawm, As-Salatu Khayrun Minan-Nawm’
(Prayer is better than sleep, Prayer is better than sleep)
Then he should complete the Adhan with ‘Allahu Akbar, Allahu Akbar, La ilaha illa Allah’."

(Reported by Dar Qutni, Ibn Khuzaymah in his Sahih – but without mentioning the repetition.)

Key Lessons from the Hadith​

➊ Saying "As-Salatu Khayrun Minan-Nawm" Twice in Fajr Adhan Is Sunnah​

• This phrase should be said after ‘Hayya ‘ala al-Falah’ in the Fajr Adhan.
• If a Mu'adhin forgets to say it, the Adhan is still valid, and there is no issue.

➋ The Importance of Prayer Over Sleep​

• Sleep is a necessity for human health, as it refreshes the body and strengthens immunity.
• However, excessive sleep can lead to laziness and harm one’s religious and worldly life.
• Prayer brings countless benefits, and increasing voluntary prayers (Nafl) leads to closeness with Allah.

Narrated by Anas (رضي الله عنه):
"The Prophet (ﷺ) commanded Bilal to repeat the phrases of Adhan twice and to say the Iqamah in a single form."

(Reported by An-Nasa’i, Bukhari, and Muslim: 378)

Key Lessons on the Structure of Adhan and Iqamah​

➌ Adhan Should Be Recited in Pairs, While Iqamah Should Be Recited in Single Form​

  • "Allahu Akbar, Allahu Akbar" (twice)
  • "Ashhadu an la ilaha illa Allah" (twice)
  • "Ashhadu anna Muhammadan Rasulullah" (twice)
  • "Hayya ‘ala as-Salah" (twice)
  • "Hayya ‘ala al-Falah" (twice)
  • "As-Salatu Khayrun Minan-Nawm" (twice in Fajr only)
  • "Allahu Akbar, Allahu Akbar" (twice)
  • "La ilaha illa Allah" (once)
• In Iqamah, phrases are said only once (except "Qad Qamatis-Salah," which is said twice).
