Assalam alaikum, In many places in the Holy Qur'an, such as in verse 100 of Surat Tawba (9:100) and verse 110 of Surat Al-Imran (3:110) , Allah Subhanahu Wa Ta'ala praised and showed His Pleasure for the Companions of Prophet Muhammad, may Allah bless and grant him peace...the Sahaba. The behaviour and actions of the Sahaba were witnessed by the Prophet, Sallallahu alaihi Wasallam, himself and approved by him, meaning that thier behaviour was also approved by Allah, Exalted is He, as it an acceptable principle that the Prophet, may Allah bless and grant him peace, is not allowed to approve of something which is essentially wrong. Thus, we must emulate them...the Companions...in our behaviour, actions, particularly minding:-- 1) That any action we take is correct in accordance with the Shari'a. 2) To remember and think about Death often, as this helps in detaching ourselves to worldly pleasures. 3) Learning to forgive others who may have offended us in ma'amalat. 4) We should have high respect for all Muslims and desire good for them, noting that every Muslim is inviolable to another Muslim--his blood, wealth and honour. 5) Performance of the late night prayers (Tahajjud), as the Master, Sallallahu alaihi Wasallam, said:--"STICK TO THE LATE-NIGHT PRAYER FOR IT WAS THE CUSTOM OF THE PIOUS PEOPLE BEFORE YOU; IT IS ALSO A MEANS OF GETTING CLOSER TO YOUR LORD; IT WIPES AWAY YOUR EVIL DEEDS, AND KEEPS ONE FROM COMMITTING SINS"..al-Jami as-Saghir, vol.2 Hadith No. 4079.
