Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that when the Messenger of Allah (peace and blessings be upon him) would finish the prayer with salam, he would sit only for the duration it takes to recite these words, «‏‏‏‏اللّهُـمَّ أَنْـتَ السَّلامُ وَمِـنْكَ السَّلام تَبارَكْتَ يا ذا الجَـلالِ وَالإِكْـرام» ‏‏‏‏ "O Allah, You are Peace and from You is peace. O Possessor of Majesty and Honor, blessed is Your Being."
