This Hadīth states that it is from the Sunnah of the Messenger (may Allah's peace and blessings be upon him) to lie down on one’s right side after praying the two Rak‘ahs before Fajr. He is to remain in this position until the Iqāmah for the prayer is called. The wisdom behind lying on one’s right is so that the person does not fall asleep, since the heart is located on the left side of the chest. When a person lies down on his left side, he is more prone to falling asleep, because he will feel more relaxed.
