In How Many Rakats One Must Give Salam In The Nafl Prayers Other Than Rawatib Sunnahs?

In how many rakats one must give salam in the nafl prayers other than rawatib sunnahs?

According to the Hanafi school, it is more virtuous to give salam once in every two rakats in the nafl prayers established at night, and once in every four rakats in the nafl prayers established in daytime. It is makruh to establish more than four rakats with one salam in the nafl prayers established in daytime, and more than eight rakats with one salam in the nafl prayers established at night (Mawsili, al-Ikhtiyar, I, 231-233; Aliyy al-qari, Fath Bab al-‘Inayah, I, 331).

According to the Shafi’i school, one should give salam once in every two rakats in the nafl prayers established both at night and in daytime (Mawardi, al-Hawi, II, 289; Marghinani, al-Hidayah, II, 37, 38).
