Have an Angel Make Dua for You

The Messenger of Allah (sal Allahu alaihi wa sallam) said: “Whoever visits the sick, or visits his brother in Allah (faith), a caller calls out, ‘May you have goodness and your livelihood be good, and may you dwell in an abode in Jannah.’” [Tirmidhi]

There are two reasons given in this hadith that cause Allah (subhana wa ta’ala) to appoint an angel to pray specifically for you. These are:
(1) Visiting a person in his illness, and,
(2) Maintaining relations with a brother/sister-in-faith for the sake of Allah (subhana wa ta’ala).

“For the sake of Allah” means to love a Muslim only because that Muslim loves Allah (subhana wa ta’ala) or because maintaining relations with that Muslim will please Allah (subhana wa ta’ala).

The angel prays for all kinds of good in your life, in particular your livelihood, and that you end up in Jannah. And since the angel is assigned by Allah, his supplication is sure to be answered by Him (subhana wa ta’ala). Visiting a sick person or a brother/sister in faith prompts an angel to make these Duas for you.
