Sri Guru Granth Sahib Ji Arth Ang 49 post 2

ਅਉਸਰਿ ਹਰਿ ਜਸੁ ਗੁਣ ਰਮਣ ਜਿਤੁ ਕੋਟਿ ਮਜਨ ਇਸਨਾਨੁ ॥
Aousar Har Jas Gun Raman Jith Kott Majan Eisanaan ||
अउसरि हरि जसु गुण रमण जितु कोटि मजन इसनानु ॥
This is the time to speak and sing the Praise and the Glory of God, which brings the merit of millions of cleansing and purifying baths.

ਰਸਨਾ ਉਚਰੈ ਗੁਣਵਤੀ ਕੋਇ ਨ ਪੁਜੈ ਦਾਨੁ ॥
Rasanaa Oucharai Gunavathee Koe N Pujai Dhaan ||
रसना उचरै गुणवती कोइ न पुजै दानु ॥
The tongue which chants these Praises is worthy; there is no charity equal to this.
