Srimad Bhagavatam 6.2.7

6.2.7

अयं हि कृतनिर्वेशो जन्मकोट्यंहसामपि । यद्‌व्याजहार विवशो नाम स्वस्त्ययनं हरे: ॥ ७ ॥

ayam hi krta-nirveso janma-koty-amhasam api yad vyajahara vivaso nama svasty-ayanam hareh

ayam
this person (Ajamila)
hi
indeed
krta-nirvesah
has undergone all kinds of atonement
janma
of births
koti
of millions
amhasam
for the sinful activities
api
even
yat
because
vyajahara
he has chanted
vivasah
in a helpless condition
nama
the holy name
svasti-ayanam
the means of liberation
hareh
of the Supreme Personality of Godhead.

Ajamila has already atoned for all his sinful actions. Indeed, he has atoned not only for sins performed in one life but for those performed in millions of lives, for in a helpless condition he chanted the holy name of Narayana. Even though he did not chant purely, he chanted without offense, and therefore he is now pure and eligible for liberation.
