قال الرسول الكريم عليه الصلاة والسلام:{من أحب أن تسره صحيفته فليكثر من الاستغفار}.

وقال عليه الصلاة والسلام :{ينزل ربنا تبارك وتعالى كل ليلة إلى السماء الدنيا حين يبقى الثلث الأخير من الليل الآخر فيقول :من يدعوني فأستجب له، من يسألني فأعطيه، من يستغفرني فأغفر له؟

وقال الحبيب عليه الصلاة وللسلام: {إن الله يبسط يده بالليل ليتوب مسئ النهار ويبسط يده النهار ليتوب مسئ الليل، حتى تطلع الشمس من مغاربها}.

و قال رسول الله صلي الله عليه وسلم "سيد الاستغفار أن يقول: اللهم أنت ربي لا إله إلا أنت خلقتني و أنا عبدك وأنا على عهدك ووعدك ما استطعت، أعوذ بك من شر ما صنعت، أبوء لك بنعمتك على و أبوء لك بذنبي فاغفر لي فإنه لا يغفر الذنوب إلا أنت " قال ومن قالها من النهار موقناً بها فمات من يومه قبل أن يُمسِ فهو من أهل الجنة، ومن قالها من الليل وهو موقن بها فمات قبل أن يصبح فهو من أهل الجنة" رواه البخاري.

قال لقمآن لابنه: {يا بنيّ, أكثر من الإستغفآر, فإنّ لله نفحآت لآ ينآلها إلا مستغفر}.

قال عـمر بـن الخـطآب، رضـــى الله عنه: {لو نـــزلت صآعقـــة من السمــــآء مآ أصـــآبت مستغفـــر}.

قال علي بن أبي طالب، رضـــى الله عنه: {ما ألهم الله سبحانه عبدا الاستغفار وهو يريد ان أن يعذبه}.

اللهم إني أتوسل بك إليك؛ وأقسم بك عليك؛ فكما كنت دليلي إليك، كن اللهم شفيعي لديك؛ وعاملني بالإحسان لا بالميزان و بالفضل لا بالعدل فإن حسناتي منك و سيئاتي مني، فجد اللهم بما هو منك على ما هو مني. آمين.

قال الله تعالى {وسارعوا إلى مغفرة من ربكم وجنة عرضها السماوات والأرض أعدت للمتقين الذين ينفقون في السراء والضراء والكاظمين الغيظ والعافين عن الناس والله يحب المحسنين}. صدق الله العظيم

قال الله تعالى {وإنك لعلى خلق عظيم}.

و سئل صلى الله عليه وسلم{ما خير ما أعطي الإنسان ؟ قال: خلق حسن}.

و قال الصحابة لرسول الله صلى الله عليه وسلم يسألونه: يا رسول الله من أحب عباد الله إلى الله ؟ قال: {أحسنهم خلقا}.

و قال عليه الصلاة والسلام: {إن المؤمن ليدرك بحسن خلقه درجات الصائم القائم}.رواه أبو داود.

و قال عليه الصلاة والسلام: {وما من شئ أثقل في ميزان المؤمن يوم القيامة من خلقٍ حسن}.

و قال عليه الصلاة والسلام: {فأكثر ما يدخل الناس الجنة تقوى الله وحسن الخلق}. صححه الترمذي وقال غريب.

و قال عليه الصلاة والسلام: {إن من أحبكم إلى وأقربكم مني مجلسا يوم القيامة، أحاسنكم أخلاقا}. حسنّه الترمذي.

و قال: صلى الله عليه و سلم {خيركم خيركم لأهله؛ وأنا خيركم لأهلي}.

و من حسن الخلق معاشرة الزوجة بالإكرام والإحترام، و بشاشة الوجه وطيب الكلام.

قال الحبيب عليه الصلاة والسلام: {كل أمر ذي بال لا يبدأ فيه ببسم الله الرحمن الرحيم ، وبالحمد لله ، أو بحمد الله أو بذكر الله ، فهو أجذم أو أقطع أو أبتر}.
