sn.1.53 Saṁyutta Nikāya (Linked Discourses)

“What is the friend of one on a journey?
What is the friend in one’s own home?
What is the friend of one in need?
What is the friend in the future life?”

“A caravan is the friend of one on a journey;
A mother is the friend in one’s own home;
A comrade when the need arises
Is one’s friend again and again.
The deeds of merit one has done—
That is the friend in the future life.”
