Number of Rakâahs for Each Prayer
3-6-2001 | IslamWeb
Question:
Tell me the number of Rakats in each Salah according to Hadiths.
Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
The obligatory prayers are five during the day and night; they are as follows: Fajr (two Rak’ahs), Thuhr (four Rak’ahs), ‘Asr (four Rak’ahs), Maghrib (three Rak’ahs), and ‘Isha (four Rak’ahs).
The number of Rak’ahs of each prayer is known through the narrations of the companions who spent many years praying behind the Prophet . This knowledge about the prayers was brought to us in the same way the Quran was brought to us. So, the prayers were brought to us generations after generations. No one has ever doubted this whether a knowledgeable person or an ordinary person.
Allah knows best.
