Breaking your fast in someone's house

If your breaking your fast in someone's house then you shall read the following dua:

أفْطَرَ عِنْدَكُمُ الصَّائِمُونَ، وَ أَكَلَ طَعَامَكُمُ الأبْرَارُ، وَ صَلَّتْ عَلَيْكُم ُ الْمَلائِكَةُ

Aftara 'indakumus saa'imuna, wa akala ta'aamakumul-abraaru, wasallat 'alaikumul mala'ikat

May those who are fasting break their fast in your home, and may the dutiful and pious eat your food and may the angels send prayers upon you.
[abu Dawud 3:367, ibn Majah 1:556, an Nasa'i]
