Peace be upon you.
‘Love for all, hatred for none ’ It is a slogan of Ahmadiyya Muslim Community. It is to show that they are not enemy to other people. It means that the real Islam teaches love for everyone and no cruelty and barbarism. It means Ahmadiyya Jamat should live with love to each other. It means the community serves humanity and conveys message of Allah to humanity because of love of humanity and to remove hatred and sow love in hearts.
The Community does so because their master Holy Prophet Muhammad (may peace and blessings of Allah be on him) taught them for it. He prayed for all humanity and helped them with kindness. His morals came from Holy Quran.
Holy Prophet (s.a.w.) came when corruption was fully spread in world.
Now in this era corruption has spread again. A part of humanity is progressing. Other part is slave. Selfishness and greed is present with at individual and international level. Currently situation is same as it was in past.
Now Hazrat Messiah Mahdi (on him be peace) came to remind morals of Holy Prophet (may peace and blessings of Allah be on him). Ahmadiyya Khalifah is teaching the path of ‘Love for all, no hatred for anyone’ and the aim is to profess
لا الہ الا اللہ محمد رسول اللہ
(There is none worthy of worship but Allah, Muhammad is His messenger.)
