﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ ٱلْكَٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ ۚ أَتُرِيدُونَ أَن تَجْعَلُوا۟ لِلَّهِ عَلَيْكُمْ سُلْطَٰنًۭا مُّبِينًا ﴾

“O you who have attained to faith! Do not take the deniers of the truth for your allies in preference to the believers! Do you want to place before God a manifest proof of your guilt?”

Maulana Ashraf ` Ali Thanavi (رح) has, in his Tafsir Bay-an al-Qur'an, taken up the question of 'standing up lazily' in the expression: قَامُوا كُسَالَ which appears in verse 142 saying: 'The laziness censured here is doctrinal laziness, (that is, slothfulness towards observance of the articles of faith due to lack of true conviction). However, laziness which is there despite correct beliefs stands excluded from the purview of this censure. Then, should this laziness be there due to some excuse, such as, sickness, fatigue or sleepiness, it is not even blameworthy. But, when without excuse, it is.'
