Five Points From Marriage 101
Safi Khan, in his “Marriage 101″ lecture CD (available from here), mentions many points; of the best, he mentions the following:
For Brothers: use extreme compassion and mercy towards your wives! Almost all relationships could benefit from more mercy and compassion. For Sisters: struggle not to complain! Once complaints start, they only get worse, and in the end, they can spoil your marriage. For Both: have a common goal–to serve Allah (سبحانه وتعالى), to worship Him, and to enter Jannah together, without reckoning.
