Answered by: Shaykh Ahmed Baazmool, Hafidahullaah
The Shaykh said; with regards to books,
(1). You should read from the Qur’âan with the Tafseer of As-Sa’ady, also the Sahih of Bukhari, Riyadhus-Saliheen, and Usool Thalatha. And as for the affair of mutual love between ourselves, we mention the Hadeeth of the Prophet, Sallahu Alayhis Salaam, "None of you will enter Jennah until we truly believe and none of you will truly believe until you mutually love each other." Shouldn’t I inform you of something that you can do and if you did it, you will increase the mutual love between yourselves. They said of course and the Prophet, Sallahu Alayhis Salaam, said, "Spread the Salaams amongst yourselves."(2). Refrain from the affairs of differing over Dunya (worldly) things, because if your heart is attached to the Akirah and what is with Allaah, then you will not dispute and fall out with your brother so easily over things that are related to the Dunya.(3). He said that you wish for your brothers what you wish for yourself and you let them know that.(4). Righteous actions in general are something that cause the hearts to become together.(5). Following the Sunnah of the Prophet, Sallahu Alayhis Aalaam, because in that is unity. The people will come together and it is the lack of adherence to the Sunnah that causes the division. And he gave an example by mentioning the Hadeeth : "Do not differ in the Salah so that your hearts will become divided." Meaning the physical things that you do, they have a real effect on the cohesion between yourselves.(6). He advised us to leave off all things that lead to division. Jealousy, hatred, deception, insulting each other and the likes. And to be patient over the harms of his brother when he opresses him or harms him. This is something that if not practiced will lead to division.
